CON-70N

On the previous text I mentioned that the Pilot Tsuwairo inks should not be used in the old converter CON-70. I am showing side-by-side pics of the old and the new versions of this converter.

Top, old CON-70. Bottom, CON-70N.

The same modifications were applied to the black version common to the urushi-based decorated pens under Pilot and Namiki brands.

There are a number of differences between them, but the one that looks more significant is the internal cylinder right behind the rubber stopper. Pilot, in fact, points at it when warning about the usage of Tsuwairo inks. The ink capacities of both versions have not changed significantly—they are 1.0 ml (with a margin of error of +-0.05 ml).

The Invisible Hand...

...of capitalism.

Pilot's converters and cartridges currently available in the market... more or less.

By the end of 2016, Pilot phased out the converters CON-20 and CON-50. And the substitute was the new CON-40.

Prices of Pilot's cartridges and converters in JPY without taxes. It is possible to find some of them at discount.

Nobody really misses the CON-50, a small piston whose problems with the surface tension were never completely solved. But many do miss the bladder-type CON-20—it was capable (0.8 ml), inexpensive (JPY 200) and efficient. The CON-40 is the opposite—small (0.5 ml), unreliable and twice more expensive at JPY 400.

Then, many an aficionado started looking for remaining stocks of CON-20 in small and out-of-the-beaten-path stationers in Japan.

CON-20 on the left; CON-40 on the right. The second is twice the price of the discontinued CON-20.

The result? In the black market –sorry, in the second hand market— the price of the CON-20 is now JPY 500.

Did Pilot make a good move discontinuing the CON-20? The invisible hand of capitalism says they did not.

Pilot 65

The Pilot 65 –or Custom 65 as some called it—is a model I have mentioned a lot on these pages, but I have never described it in detail. Given its relevance to understand modern Pilot pens it is about time to review it.

The 65 was the first (::1::, ::2::, ::3::) of those anniversary pens that later became a regular model, albeit with some minor differences.

The Pilot 65. Standard Pilot ball clip with "PiLOT" engraved on it.

So, in the year 65 of the Pilot era, 1983, Pilot launched a limited edition of 6500 pens –6460 in black, 20 in red and 20 in blue— in the well-known balance shape that many insist in associating to Montblanc. Pilot’s argument is that it follows the style of some Pilot models produced in the 1920s and 1930s, which is undeniably true.

On the cap band, the number 65 and the unit number. This was a limited edition of 6500 units.

The Pilot 65 is made of plastic with a barleycorn finish, with a wide golden cap band with an intricate decoration. The nib is made of 14 K gold and its size is not marked—this was the first of the future Custom models with a whole new set of nibs. But in actual terms, the 65’s nib corresponded to a current size 10.

The 14 K gold nib. The inscription: "PILOT / 14K-585 / < M > / (JIS):, plus the manufacturing date.

What is more interesting on this pen is the filling system—a captive CON-70 converter. Captive, I say, because it is built in the gripping section of the pen. This is, in fact, the first version of what later would become the CON-70 converter.

The captive CON-70 before this converter existed as such.

These are the dimensions of the Pilot 65 together with those of the Custom 67 and Custom 74, the natural evolutions of this anniversary pen:

	Pilot 65	Custom 67	Custom 74
Length closed (mm)	140	142	143
Length open (mm)	126	125	126
Length posted (mm)	159	160	159
Diameter (mm)	13.5	14.0	14.6
Weight (g)	17.9	18.3	22.5

The Pilot 65, with its 6500 units, is now a well-sought after collectible pen. And that seems to be the fate of anniversary pens.


My thanks to Mr. NK.

Carving

The title of this Chronicle could be a trite “yet another filling system”, for we have seen how fertile Japan has been on this field. But few truly innovative systems have survived that one model that oh-so-briefly put the system in the market. After all, cartridges and converters are truly handy and user friendly. Consequently, most of those systems are mere anecdotes. At times, though, anecdotes offer some interesting information.

The Carving pen. On the barrel there is an engraving: "CARVING / MADE IN TOKYO".
Dimensions of the pen: length closed: 138 mm; length open: 124 mm; length posted: 154 mm; diameter: 10 mm; weight: 12.6 g.

Nothing do I know about the brand “Carving”. However, the shape of this particular model, and the geometry of the nib point out at the 1960s as the production time.

A gold plated stainless steel nib. The engraving is simple: "CARVING / JIS ". The geometry is similar to some nibs made by Pilot and Sailor during the 1950s and 1960s.

Inside, something that looks like a cartridge. The inscription reads "カービンオーツマン61 / 吸入もできるスペアー" (Carving ôtsuman 61 / inhalation spare).

Its filling system also suggests an intermediate time between the 1950s and 1980s—it is an interesting middle point between two known systems. The first of them is the pulsated piston Pilot named as A-shiki (system A) in the late 1940s. The second, obviously by now, is the CON-70 converter, also by Pilot, currently on production.

On the first system –A-shiki–, the whole pumping action is driven from the tail, and a sliding sheath in the internal rod acts as stopper preventing the ink from going out on the downward movement of the system.

The system A on a Pilot from late 1940s.

The CON-70 acts in a similar fashion. Now the sealing valve is a rubber part that moves quite freely along the metallic rod in the central axis of the converter. And the basic difference with the system A is the spring that retracts the piston automatically. Well, and the fact that the CON-70, as a converter, can be detached from the pen.

A built-in CON-70 in a Pilot Custom (no additional number) from 1985. This filling system was also implemented on the Pilot Custom 65 (1983).

The “Carving” system implemented on the Carving pen works on the same principles: a pumping system and a closing valve. But now the pumping mechanism is a type of a sac, although on this case it is more of a plastic cartridge with some flexibility. The valve, on its side, moves freely inside the bladder, and seals it –partially— when pressing it. Carving called this “inhalation spare” and it makes some sense as the whole mechanism can be detached from the pen and could easily be replaced. I ignore, however, if the company marketed spare filling systems or had designed (and sold) more traditional –nominally disposable— cartridges.

The de-facto converter. The internal stopper is visible through the cracked plastic. The durability of this device is an obvious concern.

The fact that this “Carving” system was trivially detachable is, in itself, very interesting. First, because it shows that the time of the self-filling systems was ending and yielding its way to the disposable cartridge. Second, and more relevant here, because Pilot implemented the early versions of the later called CON-70 as built-in, non-removable filling systems on a couple of models in the early 1980s. In this regard, the Carving pen was well ahead of its time.

But it is also a small anecdote in the history of Japanese pens.

My thanks to Mr. Sugimoto.

Pilot Cartridges and Converters 2017

The Chronicle on Pilot converters and cartridges is the single most popular text on this blog. However, there are some misconceptions and some news, and a revision of that old text, from 2011, is in order.

The current situation is as follows: Pilot markets three different converters and two different cartridges. Two of the converters reported in 2011, CON-20 and CON-50, are discontinued.

The three converters on production are named CON-40, CON-70, and CON-W. The number refer to their price in Japan: JPY 400 for the CON-40, and JPY 700 for the CON-70. The CON-W only works on the pens that implemented the "double-spare" cartridge in the 1960s. Nominally, it is only served as a spare part and some retailers demand the “broken” pen to be sent for fixing. However, Maruzen and Itoya at their main shops in Tokyo (at least) sell the CON-W without any problem. Its price is JPY 700.

The new guy in town, the CON-40. It holds about 0.5 ml of ink and costs JPY 400.

All the cartridges and converters covered on this Chronicle. From left to right, CON-70 in steel and in black, CON-50 new and old, CON-40, CON-20, two "single spare" cartridges, two Petit cartridges, CON-W. With the obvious exception of the CON-W, all of them share the same mouth dimensions and, provided they could fit inside the barrel, could be used in any "single spare" cartridge/converter Pilot pen.

As for cartridges, the two types are the regular one, formerly named as “single-spare”, and the cartridge specific for the Pilot Petit pens (::1::, ::2::, ::3::). Single spare cartridges do not fit inside the Petit pen, and the only problem of the Petit cartridges to fit in regular Pilot pens are two small plastic notches at the opening of the cartridges. They can easily be removed with a blade.

Petit cartridge on top. Single spare cartridge on bottom. Note the small notches on the former. They prevent the use of the small cartridges on many Pilot pens that, otherwise, could use them. Removing them is easy with a blade.

The following table summarizes the present situation and includes the data of the recently discontinued converters CON-20 and CON-50.

Pilot Filling Systems in the 1960s

Armed with the information on the way of dating not just the nibs but the whole pen –even if only during only twenty years—there are a number of observations to be done. One is about the filling systems implemented by Pilot during those critical years.

Let us remember that Platinum had released the first Japanese ink cartridge in 1956, thus opening the path for most Japanese pen companies. At the time (mid to late 1950s), Pilot was using sac-based systems—either the original hose system (also known as quarter switch) or a more traditional aerometric for thinner and smaller pens of the Super series. Later on, already in the 1960s, Pilot created its own ink cartridges while preserving the sac-based systems and even implemented another system—the bellow filler with an accordion sac.

The following chart shows how all these systems coexisted during the 1960s in the Pilot catalog. The data on it are based on my own accounting, and are based on documental evidence. Therefore, they can hardly be final, as there could be earlier and later examples of these systems.

Some notes on the graph:

1. The latest unit I have found of the Hose System was manufactured on September of 1964. Later units of this system could exist.

A Hose System in a Super Ultra 500 from 1959.

2. Few units implemented the Bellows Filler (accordion sac) and therefore it is difficult to establish definitive starting and ending data, which on the graph are set as July 1965 and December 1969. This system seems to have been the last sac-based system implemented by Pilot.

A Pilot Super 500G with a Bellows Filler system.

The Double Spare cartridge.

3. The first Double Spare (DS) cartridge I have seen is associated to a 1963 model of the Capless (C-600MW) dated on April 1964. However, it is safe to assure this ink cartridge existed since, at least, November of 1963, as this was the release date of this model. Earlier pens could also have used this cartridge.

The Single Spare ink cartridge, the current Pilot's standard ink cartridge.

4. The earlier pen implementing the Single Spare or single cartridge (SC) –that is, the ink cartridge currently on production— I have found was manufactured on May 1964.

An interesting conclusion of this chart is the fact that DS and SC were initially marketed almost simultaneously. Consequently, the SC was not the successor of the DS. These two systems coexisted despite their incompatibility for a about six years.

And my text on the Double Spare cartridge was wrong.

Out of Production (II)

When speaking about the problems to find proprietary cartridges to ink a Morison pocket pen, I ended the text with a negative conclusion—those pens, that Morison for instance, lose a lot of value in the second hand market, those pens have become almost useless.

The Morison pocket pen whose cartridges are almost impossible to find.

But there is also a positive conclusion—some brands still provide support for their old products. That is the case of the three big Japanese pen manufacturers with regard to the very popular idea of pocket pens. Current ink cartridges by Pilot, Platinum and Sailor can be used in those pocket pens from the 1960s and 1970s. In fact, cartridges are the only way to ink some of those pens, mostly Platinums and Sailors, as the old converters went out of production. Pilot is particularly exemplary on this—the CON-20 converter fits perfectly on those pocket pens and is a good alternative to cartridges. And Pilot, as well, still produces the CON-W to be used on those old pens (1960s) that needed the long gone double spare cartridges.

The original Pilot Myu-701 and its reissue, M90, can use the CON-20 converter.

The Pilot Capless from 1965 can still be used todays, in absence of double spare cartridges, by using the CON-W converter.

Some could say that the only difference between Morison and the big three is that Morison is out of business. And that is true, but true as well is the fact that some still-active companies did abandon some of their old products. Case in point, the beautiful Waterman C/F pen uses a specific type of cartridge and converter now out of production. And this makes us value a lot more those other companies.

The Waterman C/F, equipped with its converter, now almost as valuable as the pen itself.

For those unfortunate cases we have two options. The obvious is to look for those old cartridges and converters in second hand shops, flea markets and online auctions. The other is to adapt other ink deposits. That is what I did with my pocket Morison. Now it is inked with an adapted Pilot cartridge.

But the bottom line might be that self filling pens and eyedroppers do not have this problem.

Out of Production (I)

I can think of a very big reason to rather self-filling over cartridge-converter. With self-filling pens, the owner will never run out those essential elements, cartridges and converters, to use the pen. An acceptable alternative might be standard/international cartridges whose manufacture is shared by a big number of companies.

A Morison pocket pen from the 1970s.

The risk is clear—should the maker of that particular pen disappear, its proprietary cartridges and converters might also become extinct from stationery shops. That is the case of the following Morison. It is a well made pocket pen with a semi-hooded 18 K gold nib. But it uses Morison-proprietary cartridges, long gone and very hard to find after the company stopped the production of pens in the early 1990s.

In an attempt to ink this pen, I tried to use Sailor slim cartridges (for the Chalana model). These are thin enough, but too long to fit inside the barrel. On the side, the plastic tassie of the barrel.

Some other models of this brand can use Platinum cartridges, and in fact, the cartridge nipple of this pen accepts Platinum cartridges, but not the rest of the pen. Its body is too small –both short and narrow— to host it. And neither can this Morison be used as eyedropper as the tassie at the back of the barrel does not seal the body and can easily be removed.

Therefore, this pen is not usable without the proper –and missing—cartridge or converter. And it is frustrating as the pen is in perfect working conditions with only minor cosmetic defects. This issue obviously reduces the value of this pen in the second hand market.

Honest 66 Cartridge

In 1956, Platinum introduced the ink cartridge in Japan. To do so, the company marketed a modified version of the model Honest, an aerometric filler, under the name Honest 60, and the cartridge was labeled as Honest Cartridge. Many a pen brand adopted it for its pens and thus it became a standard. That was the case, for instance, of Mitaka and of Nobel’s, the later being another brand worth to write about.

The picture shows the initial Honest 60 cartridge, on top, and the current Platinum cartridge, on bottom. Note the differences in the area where the cartridges attached to the section.

That initial cartridge immediately went through some minor changes in the opening. By 1960, a further evolution of the Platinum pen, now called Honest 66, provided a larger and longer barrel where a bigger cartridge could fit. That was the Honest 66 cartridge. Unfortunately, this was short lived, and only the smaller version is available today.

Both cartridge/converter Platinum Honest pens. The Honest 66 (1960) on top, and the Honest 60 (1956) on bottom. The nipple of the former is well inside the section, thus allowing more room for the longer cartridge.

Both cartridges and the current converter. This has a capacity of 0.6 ml (0.53 ml according to the Platinum catalog).

The Honest 66 cartridge had a capacity of 1.7 ml, while the regular Platinum cartridge only holds 1.2 ml.

Double Spare

In 1956, Platinum marketed the model Honest 60. This pen was the first ever cartridge-converter pen in Japan and, therefore, saying good-bye to ink bottles implied the development and marketing of ink cartridges—the Honest cartridge.

Two double spare cartridges, connected. They can easily be detached from the central piece.

Pilot reacted to this innovation with its own line of cartridges. It was called “double-spare”--two independent ink cartridges held together by a plastic central piece. The merit of this system, Pilot claimed at the time, was that the user would hardly ever run out of ink—not even in the most difficult situation. Once the working cartridge was empty, plug the spare one in, and, back home, replace the former. Smart, but it is not that inconvenient to carry some spare cartridges in your pocket, especially during those critical situations.

A 1963 Capless, first Capless model, with the "double-spare" cartridge.

The system was short lived. It might have started around 1962, and in 1968 it was phased out. But a number of pens, of interesting pens, were produced during those years. Among them, all the Capless models up to 1968. Finding these “double-spare” cartridges is now very difficult, either used or new, and the modern solution is to use the CON-W converter, still included in Pilot’s catalog and available at some shops in Japan.

Pilot converter CON-W.

However, the most interesting feature of these cartridges is that they provide an easy way to date some Pilot pens—any double-spare belongs to this 1962-1968 period. And any pen with the “single-spare” cartridge –such was the initial name of the current cartridge design by Pilot— is from a later date.

CORRECTION (2013/09/20): There are double-spare pens up to, at least, 1969. And the single spare cartridge appears in the market as early as in 1964, if not earlier. Please, check the Chronicle Pilot Filling Systems in the 1960s.

CON-50

In my personal experience, out of the three ink converters Pilot produces for the current line of pens, the piston CON-50 was the least satisfactory. Too often, the ink’s surface tension prevented it from reaching the feed, thus causing a lack of ink supply on the nib. Shaking the pen was the obvious solution, but there is always some risk of releasing an uncontrolled drop of ink. Needless to say, Murphy’s Law does apply here.

More modern (that is, included on the 2012 catalog) CON-50 come now with a variation with respect to the older model: there is now a metallic piece inside the converter. The idea behind it is similar to that of the ball inside some ink cartridges—to break any possible ink drop on the converter or cartridge walls. The cost of this solution is a small reduction in the ink capacity: from 0.7 ml to 0.6 ml, according to my own measurements. The price of the new CON-50, however, has not changed: JPY 525 (5% tax included).
