Early Pilot Nibs. III. Size 1

Size 1 nibs by Pilot are not that different in size to those of size 0. Here we can see the dimensions of two size-1 units:

Manufacturing date	.Oct 1955.	.Nov 1937.
Length (mm)	21.7	22.7
Width (mm)	5.3	5.8
Feed diameter (mm)	5.0	5.0
Weight (g)	0.2 - 0.3	0.3

Dimensions of two Pilot nibs of size 1.

Nib made on November of 1937. "WARRANTED / "PILOT" / 14 K / MADE IN JAPAN / -<1>- / HARDEST / IRIDIUM".

Nib made on October of 1955. "WARRANTED / PILOT / 14 K / -<1>- / MADE IN / JAPAN".

There are some obvious differences between these two units made 18 years apart. And the feed diameter seems even smaller than that of the size 0 nib described some days ago.

The engravings of these two nibs are very similar, but this detail changes with the manufacturing date, as we will see along this series of texts

Early Pilot Nibs. II. Size 0

Among early –pre-1955—Pilot nibs, size 0 seems to be the smallest of them. I have only seen it made of 14 K gold.

These are its dimensions, but these data should not be taken very strictly—manufacturing processes, quality controls were not as they are today, and some variations over these measurements should be expected:

• Length: 20.6 mm
• Width (shoulders): 5.2 mm
• Weight: 0.25 g
• Feed diameter: 5.1 mm

This particular nib was manufactured on February of 1935. The engraving reads “WARRANTED / “PILOT” / 14 K / MADE IN / JAPAN / -<0>- / HARDEST / IRIDIUM”.

Early Pilot Nibs. I. Introduction

Few things are standard in the world of fountain pens. Each pen brand seems to create its small world with its own systems of names and measurements. A very clear example of this lack of standards is the way pen makers number their nibs. Many aficionados as well as traders simplify the wide gamut of Bock nibs as being of sizes 5, 6 or 8, which are, in actual terms, the diameters of their corresponding feeds. But those numbers have little to do with Pilot’s –to name just one company— nibs labeled as 3, 5, 10, 15, 20 and 50. Sailor and Platinum, on their side, do not even bother to number their nibs nowadays.

Sailor nibs in three different sizes.

Four modern Pilot nibs in size 15.

In the early days of Pilot, the numbering system was very different: from 0 to 8, with the possible exception of 7, plus 20 and 50. Now, do those numbers mean anything?

With this text I am starting a new series of Chronicles aiming at describing all these nibs, and to analyze whether those numbers really meant anything. This is, needless to say, a work in progress.

Four Pilot nibs from the 1920s. They are labeled as sizes 1 and 3.

One additional note: The title speaks of “early” nibs. By that I mean all those nibs that followed a more or les consistent system of numeration. This came to an end with the implementation of the Super model in 1955. Up to that year, the vast majority of Pilot pens sported open nibs (i. e, showing the feed as well) labeled with what seemed to be a normalized numbering. Therefore, “early” means, more or less, before 1955. And implicit on this classification is the hope that those standards were maintained over all those years.

This series is a joint effort of some pen enthusiasts who offered their assistance to compile all the information. Their names are N. Syrigonakis and A. Zúñiga.

Sailor in Osaka

The following pen is a limited edition. It is a Professional Gear Realo made, needless to say, by Sailor, but it is not a regular Sailor pen. This model in matte black and red was commissioned by a group of pen users from Osaka organized as the YY Pen Club.

An unusual and very limited Professional Gear Realo.

Some more surprises on the nib...

And there are more variations beyond the unique –so to speak— coloring of the pen: the nib is not engraved with any sign save with the gold purity –18 K gold— and the nib point. 18 K is not the usual gold grade implemented by Sailor on its pens (save in the case of the ultra-thin Chalana), but we have already seen 18 K Sailor nibs on Davidoff’s pens.

Unmarked nib, save for the gold purity and the point width.

A very interesting detail here is how keen Sailor is to make limited editions for whoever demanded it. It seems that the basic order is of just 10 pens. On this particular case, YY Pen Club ordered 30 units, not numbered. Its distribution is only done through that club of pen users. In that regard, this is not so much of a limited as it is a commemorative pen for a private organization.

My thanks to Mr. Sunami.

Datation of Japanese Pens. VI. Sailor's Bodies

On the previous Chronicle we have seen how the manufacturing date is codified on Sailor nibs. But that is not the only dating system used by Sailor—pen bodies were also dated for some time.

Between 1958 and some time around 1970, Sailor pens had their sections engraved with a two letter code, either or in lower or in upper case:

YZ

(Occasionally, there is a period between the two letters).

On it, Y stands for the year of productions following a simple rule: A (or a) is 1958, B (b) is 1959, C (c) is 1960, and so on. Z is the month of production, with A being January; B is February and so on.

This pen is encoded as C.E--May of 1960. It corresponds to the pen shown on the following picture.

This is the Jubilee pen made by Sailor on the occasion of its 50th anniversary (1961). This particular unit, as we saw on the previous picture, was manufactured on May of 1960.

This system, as said before, lasted until ca. 1970, when the system changed to a three digit code identical to that used on the nibs: abb, where bb is the month and a is the last digit of the year of production.

This 3-digit system did not last long. On my records I can only see it between 1971 and 1974. As a result, modern Sailor pens carry no dating code on their bodies

This pen is dated as 109, which might mean September of 1971.

This is the nib of the previous pen, which is one of the rare examples of dual datation. On this case, the nib carries the manufacturing date of 108--August of 1971. 1971 seems a very reasonable date of production given the fact that the nib is made of 23 K gold, and the gold fever of the Japanese pen makers took place in the early 1970s.

The previous pen, posted. A 23 K gold nib in a pocket pen.

Another interesting detail is that it is very rare to see a (Sailor) pen dated on BOTH nib and body, although there are some few examples of dual datation.

My thanks to Mr. Sunami.

Datation of Japanese Pens. V. Sailor Nibs

Some time ago I published several texts with information on how to date Platinum and Pilot pens. Sailor also has its own dating systems for nibs and pen bodies, but they are less obvious than those of the rival brands.

Sailor pen nibs have consistently been engraved with a three digit code in the form

abb.

On it, bb –from 01 to 12— stands for the month, and a –from 0 to 9— is the last digit of the year of production.

This nib is dated on 710--October of some year ending in 7. And later than 1954, when the JIS stamp was engraved on pen nibs. It belongs to the following pen.

A bulb-filler previous to the time of cartridges and converters. Most likely, therefore, made in 1957.

Needless to say, this system is not so precise as those seen on Pilot (::1::, ::2::) and Platinum pens. Sailor, so to speak, demands some additional knowledge on the pen model in order to decide whether that 3 (for a) meant 2013 or 2003 or, even, 1993.

This Ohashido nib, by Sailor, was made on November of 2014. The nib was not yet attached to any pen. The picture was taken during the last Fountain Pens of the World Fair at Mitsukoshi Nihonbashi.

Ohashido nibs, currently made by Sailor, also display this dating code. However, not all Sailor nibs are dated—just most of them.

Pilot Capless - 1984 - FCN-500R. I. Introduction

In the evolution of the Capless model by Pilot, things become a bit more complicated in 1984. Up to now, each model used its own nib unit and the nib units were not usable in other models. Some nib units, though, showed a number of variations, but their use, should I insist, was limited to a particular Capless model. An obvious example of this is that of the RW models from 1965, whose nib units had up to four different variations.

That changed in 1984. The model encoded as FCN-500R implemented the same unit as its predecessor CN-400BS. Later on, around 1990, the nib unit was redesigned, but keeping the basic geometry that allowed its use in all models made after December of 1973 (from CN-400BS on).

These units can be used in all Capless models made after December of 1973.

In actual terms, it is questionable whether this 1984 FCN-500R constitutes a new model or it is just a cosmetic variation of the previous one. The similarities are very obvious, starting, for instance, by the nose-clip piece made of aluminum.

Different models or just variations? On top, the CN-400BS from 1973; on bottom, the FCN-500R from 1984.

But for the sake of these texts, these variations or models will be considered as separate models. Otherwise, all Capless after 1973 should be considered as variations of the CN-400BS with the only possible exception of the Fermo model (FDF-2MR) of 2006. And if so, the description of all of them would be unnecessarily complicated.

All these models use the same nib unit. From top-left to bottom-right, CN-400BS (1973), FCN-500R (1984), FC-15SR (1998), FCT-15SR (Décimo, 2005), and FDF-2MR (Fermo, 2006).
