Dimensions of three Pilot nibs of size 2 made of 14 K gold.
From 1953. Note the JIS mark. The feed of this pen, and of those of the 53R models (1950s) are slightly thinner on the area attached to the section.
As can be seen on the pictures, there are size-2 nibs made of steel. The exact dimensions of these units are not available—the integrity of the pen is still more important that those data.
The engravings on the nibs, as was the case with other sizes, show a clear evolution along the years of production.
Pilot Justus, 1979 model – Pilot Blue

Hello
Could the changes be down to re-tooling, post 1945, with new machines in new factories?
That is a likely explanation, but I cannot support it right now.
Thanks for passing by and commenting.

What do you mean by preserving pen integrity?
Thanks, Anonymous, for passing by and commenting.
When measuring some dimensions of a nib, particularly the shoulder's width, you might be afraid of deforming the nib with your caliper. Being too careful might result on larger measurement.
