Chilton Violet

After having seen a great number of filling systems on Japanese pens, both imported from the West (::1::, ::2::, etc.), and originated (::1::, ::2::, ::3::, to name just a few) in Japan, it will be no surprise to find yet another one.

This time, the pen –by the name of Violet— implements the pneumatic filling system initially created by the Chilton Pen Company in 1925. This Japanese pen, however, was manufactured in the early 1950s.


On the barrel, '"VIOLET" / TRADE MARK / Fountain Pen'. And a very Parker clip.

As for the rest, the nib is made of steel and does not carry any reference to the pen brand, which raises the concern of whether this nib was the original unit of this pen. However, that is not the relevant feature of the Violet.


The nib, made of steel, carries the following inscription: "WARRANTED / EASY / BEST / PEN / 1". This unit could be a replacement.

These are its dimensions:

Length closed: 121 mm
Length open: 105 mm
Length posted: 142 mm
Diameter: 11 mm
Weight (dry): 11.5 g


The barrel extended, the pen ready to be filled.


The hole at the barrel end typical of pneumatic fillers.

This pseudo-Chilton Violet is a rare pen even in Japan, but it illustrates the great variety of filling systems explored by Japanese makers long its more than 100 years of history.

My thanks to Mr. Sunami.

Wingflow by Platinum

I finished the previous Chronicle with the picture of a recently purchased music nib by Platinum. That pen truly calls for a detailed presentation, but its nib is interesting on its own merits—long lasting merits. For this nib design is still in the market, forty years (at least) after it was initially released.


The Platinum music nib I mentioned on the previous Chronicle.

In fact, that music nib might very well be one of the first examples of this design together, of course, with more standard points. That was around 1973. Since then, that nib has been implemented in a number of pens, including some early Nakaya (2001), and has been cast in many different materials: steel, 14 K and 18 K (yellow) gold, and 14 K and 18 K white gold.


Three examples of this nib design made in three different materials. From top to bottom: 14 K yellow gold, 14 K white gold, and steel.


The same nib, now in 18 K gold, was implemented in this "exotic skin" series of Platinum pens from the late 1970s. This particular unit was produced in August of 1978.

As of today, in 2013, this design, made in steel, can be found in some (relatively) inexpensive Platinum models: Balance/Cool, Affection, and steel-nib Standard. On more upscale models –Sheep, gold-nib Standard, and some low end maki-e pens— we can see it made of 14 K and 18 K gold. However, on all these models only two nib points are available: F (細) and M (中).


The Platinum Cool uses a steel version on this nib. On the picture, with a fine (細) point.

Forty years in the market make a good argument. But how do these nibs perform? They are very rigid with just a hint of bending under pressure, but they are unbelievable reliable. They do write on contact, and are never shy to speak out.

On this design the nib edges wrap around the feed and fix their relative positions. This geometry was not new or unique. It could be seen as early as in 1935 in the Chilton Wingflow pens. The claims of this manufacturer were that this shape of the nib ensured “perpetual factory precision adjustment of point and ink feed”, while “it creates a reserve pocket for ink”. However, many argue that the main point of this design was to reduce the amount of gold in the nib. But Chilton closed down in 1941, and Platinum and is still here producing wing-flow nibs for over forty years. In fact, for longer than that, albeit with different designs now no longer available.


Two units of this wing-flow design by Platinum.

Now, the question is, once again, whether we needed gold nibs or, given the stiffness of these nibs, much cheaper steel nibs would suffice.

My thanks to Mr. Furuya.
