1481 - the world's earliest dated handgun

[Matchlock]

Hello, Alexander,

The measurements you requested are as follows:

A = 4.8 mm, B = 5.2 mm, C = 4.2 mm and D = 5.4 mm.

I attach a characteristic late 15th century form of a stock that would ideally complete this barrel. As the barrel was originally painted red (and still is underneath the black layer), a dark green paint on the stock would convey a perfect impression of late Gothic color taste.

Best,
Michail
