10 Years

War restrictions in Japan in the 1930s and 1940s severely reduced the availability of some metals for the pen industry. As a result, most (if not all) nibs at the time were made of steel. These are the “shiro” nibs that have already shown up on these chronicles.

After the war, the availability of gold was slowly increasing and some luxury pens were equipped with nibs made of this noble metal. However, many a company played the trick of confusion between gold plated and actual solid gold nibs. The official response came from the almighty Ministry of Industry (actually, the Ministry of International Trade and Industry, MITI): The Industrial Standardization Law was enacted in 1949 and by 1954 the Japan Industrial Standards, JIS, logo imprinted on nibs guaranteed the material out of which they were made.

Platinum (Platinum Sangyo Co. Ltd. at the time), on its side, created the 10 year guaranteed nib in 1953 after perfecting the manufacturing process. Let us remember now that the main argument for the use of gold over steel is the much higher resistance to corrosion of the noble metal.

On the left, the Platinum Honest 60 nib. On the right, that of the Presidente. Both are identical "10 Years" nibs save for the obvious gold plating of the later.

On these chronicles, paradoxically, the first encounter with a 10 year nib by the hand of the nominally Spanish pen Presidente. Of course, we now know that it was a variation of the Platinum Honest, whose nib, we could also see, was also engraved with the "10 years" sign. But these are not the only examples. 10-year nibs were made in a number of shapes and sizes, and these are some examples.

These nibs belong to an aerometric Honest (left), to a copy of the Parker 51 (center) and to an oversized luxury lever filler (right).

Built-in

I have already reflected on these chronicles on the appeal of self-filling and other arcane systems among stylophiles (see, for instance, chronicles Sailor´s Piston, and Romanticism). Cartridges and converters are often frown upon non very clear basis other than a diffuse and romantic idea of what a fountain pen should be.

Now, what would happen if we attached a converter permanently to the section of the pen? Would stylophiles value that creation as a pen loyal to the essence of a pen? Would that be a real self-filling pen?

Pilot Custom from 1985.

This Pilot Custom from 1985 illustrates this idea. From outside, it really looks like a self-filling pen—few cartridge-converter (C-C) pens implement an ink window despite the fact it could be very useful in combination with some metallic converters. Then, opening the barrel, we see that it indeed is a self-filling pen. And the (transparent) filling system is truly original.

Pilot Custom, from 1985. The ink window is clearly visible, although is hidden by the cap when the pen is closed.

Or is it?

It is a pulsated piston, and it is also a built-in CON-70 converter.

The filling system, exposed.

As for the rest of the pen, it is made of black plastic with golden trim. The nib, in 14 K gold, is equivalent to the current size 5 available on several Custom models. Not a fancy pen save for the filling system. But is it enough for stylophiles to appreciate it as a real self-filling pen?

The nib, in 14 K gold, is similar, if not identical, to the currently produced size 5.

Detail of how the filling system is integrated in the section.

What if we glued a converter to the section of any C-C pen?

All this shows, once again, that cartridges and converters were a natural evolution in fountain pens. But of course we are romantics, and as such we are not very prone to rational arguments.

Unnumbered

We encountered the Platinum Honest 60 pen at the time of understanding the Japanese origins of two apparently European brands: the Italian Joker 60 and the Spanish Presidente. The Platinum Honest 60, let us remember now, was the first cartridge-converter (C-C) pen ever marketed in Japan. That was in 1956. In previous years, some sources said, there existed some self-filling Honest pen models.

The Platinum Honest. The sticker says, in katakana, "puratina (Platinum) / Y400 / onesutopen (Honest Pen)". The barrel is engraved with a similar script, but in alphabet: "PLATINUM / (Platinum logo) / HONEST PEN".

Such is the pen on display today—a Platinum Honest (no figure) with an aerometric filling system. This pen is remarkably similar to the first Presidente pen described on these Chronicles. Same grey color for the body, same gold plated steel nib, same barrel and section. The basic difference is on the cap jewel—on the Presidente, the jewel had the old Platinum logo engraved; on this Honest the logo is engraved on the clip, just by the black top jewel.

The Platinum logo, on this pen, is not engraved on the jewel but on the clip.

The nib is a "10 year" made of steel. These nibs will be the topic of another Chronicle.

Close up of the nib. The inscription reads "PLATINUM / 10 YEARS / (Platinum logo) / (JIS logo) - 5". The Presidente's nib inscription was the same save for the last number: a 11.

These are the dimensions of the Platinum Honest and of the first Presidente:
.................................Honest Pen............Presidente
Length closed:............. 132 mm..............134 mm.
Length open:.................118 mm..............123 mm.
Length posted:..............145 mm..............150 mm.
Diameter:.........................10 mm................10 mm.
Weight (dry):.....................14.0 g.................14.5 g.

The Honest pen, disassembled.

The instructions to fill the pen are in English: "PLATINUM HONEST PEN / TO FILL INK. PRESS SPRING BAR / FIVE TIMES. USE PLATINUM INK".

This Honest pen, with no numbers, is an earlier model than the cartridge-converter Honest 60, and it is obvious origin of the European pens Joker and Presidente (and eventually a German Senator following the same pattern, if my information is correct). The Presidente brand was registered in Madrid in 1959, years later than the launching of the Honest 60 in 1956. What we still do not know is whether these aerometric fillers were phased out in Japan because they were considered obsolete after the C-C version had been released. If so, those European Platinum were a good way to get rid of those old pens.

Capless 1965

The Pilot Capless is not just one pen but a whole saga with a long history. Since it was initially marketed in 1963, the pen named as Capless or as Vanishing Point has gone through a number of changes that actually conformed different models. Some of them have already been described on these pages: 1964 (More Capless), 1968 (Gravity), 1971 (Capless 1971).


The Capless I am showing today was initially marketed in Fall 1965, and was the last model in using the old double spare type of ink cartridge. Therefore, it uses the CON-W converter. The next model, from 1968, already implemented the Pilot cartridges currently on production.

This Capless is made of aluminum and adopted several finishes. This one has a subtle golden color, like if it had been gold plated with a very thin film of this metal.


The mechanism to release the nib is not by means of a push button but by twisting the lower half of the pen. Its bottom end is made of black plastic and has no special function on the nib operation.


The nib is made of 14 K gold and has no indication of the point. It is engraved with the production date: Hiratsuka, January 1968. This nib unit is not compatible with any other model of the Pilot Capless.


These are its dimensions:

Length closed (retracted): 140 mm.
Length open (extended): 145 mm.
Diameter: 12 mm.
Weight (dry, with converter): 20.4 g.
Ink deposit (CON-W converter): 1.1 ml.

Three (Japanese) Swans

Nobuo Itô's Swan become the most successful pen company in Japan around 1920. Its strategy was simple—copy the looks and style of the pens made by Mabie-Todd in England under the name Swan, the real Swan, and let the Japanese government protect you from foreign legal disputes. As we have already seen, even the logos were blatantly similar.

Three Japanese Swans.

This company, though, was deeply affected by the Second World War –its production plant was destroyed—and finally it ceased its activities in the early 1950s, unable to compete with the myriad of pen operations active at the time in Japan.

Their nibs are not completely the same. Note the differences in the breathing holes.

Neither are their feeds the same.

The three pens I am showing today belong to the later period of the company. They are made of celluloid and are quite transparent—the sac and the nib can be seen through the barrel and the cap. Their filling system is a lever filler. The nibs are made of steel, partially gold plated, and are quite rigid.

The engraving on the nib reads "Swan / Manifold / Fine / Swarosmine / (Swan logo)".

They are not exactly the same in terms of dimensions and nib design, as can be seen on the pictures. These are their dimensions:

Length closed: 124-126 mm.
Length open: 112-114 mm.
Length posted; 149-154 mm.
Diameter: 12.5 mm.
Weight (dry): 13.0-13.7 g.

The Japanese text just says Swan fountain pen.

The original price of these pens were JPY 350, as can be read on their original stickers.

Size 6

Hoshiawase (星合せ) pens have already been covered on these chronicles. And although they are indeed original and interesting —albeit a dead end in the evolution of pens— there is only that much you can say about them. Once the description of the sealing system of the ink deposit, remember these are eyedropper pens, the rest is merely an account of the nib characteristics and of the body material and decoration.

However, that might be the fate of most fountain pens. After all, few truly innovative features there existed on this world, and those have been implemented on many different pens. In this regard, the star system has the merit of having been used only by Pilot.

The BCHR eyedropper by Pilot, from 1924.

The size 6 nib. On the section, the two stars can be seen uncrossed. Therefore, the ink channel was open.

Today´s hoshiawase pen sports a big nib—a size 6 nib. Although not the biggest for these pens, some size 8 have been reported, this is indeed a remarkable and rare pen. It dates from 1924, and its sealing system shows the earlier scheme of the hoshiawase.

An early form of hoshiawase. The element limiting the rotation of the cylinders in the section is very exposed. On later pens, this element was encircled by a groove on the outer cylinder.

As for the body, it is a black chased hard rubber (BCHR) pen.

All the elements in this pen are in pristine condition, and I doubt the owner would ever ink it.

My thanks to Mr. Niikura and to FPN member Nikolaos.

Shut-off Valve

Eyedropper pens with shut-off valve are a very Japanese idea, we all know by now. This idea is, in essence, a simplification of the plunger filler implemented by Onoto on the fountain pens arriving in Japan around 1900. The plunger filler is no longer there, and the tail knob now operated the axis moving the cone that opens and closes the connection between the ink deposit and the section.

Mostly all Japanese companies used this mechanism at some point. Some examples have been shown on these chronicles: Asahi-Tsubasa, Ban-ei, The Eiko, New Clip, Pilot-Namiki, Platinum, Platon, SSS, (Japanese) Swan,… As of today, Pilot-Namiki, Nebotek and Danitrio still make this type of shut-off valve.

SSS in black ebonite. The sealing cone is visible inside the barrel.

Swan (Japan) number 5. The section is disassembled from the barrel. The sealing cone and its axis are visible.

However, my experience using these pens is very limited. Their weakest point is the seal between the axis and the top end of the ink deposit. This thin rod must slip up and down through this seal to allow the ink to pass through the valve to the section and the feed. Traditionally, this seal was made of cork and lack of use and the passing of time are good arguments for ink leaks. In such case, these pens become very messy—ink would leak through the tail knob when turning it to open the valve.

The tail knob of the Danitrio Ban-ei.

After trying with some vintage pens –a SSS made of ebonite, with stained results—I decided to ink a Danitrio Ban-ei. Being modern, it is in good shape and there are no leaks. Then, how does it perform?

Its nib is a very smooth unit made by Kabutogi Ginjiro. It is nicely wet—as long as the there were ink actually flowing through the feed. So, in principle, this pen performs well—open the valve, uncap the pen, write. However, sealing the ink deposit when not in use has some side effect—the nib quickly becomes dry. My contention is that the lack of connection between nib and deposit deprives the first of a permanent supply of ink. Then, the natural evaporation simply dries the nib up and this space cannot be refilled with more ink from the deposit. If stored with the valve open, the nib does not become dry.

I wonder if that was the case with other eyedropper pens with shut-off valve.
