I have some drawings I got from the Smithsonian National Archives years ago. The drawings are scaled 1:1, but there are no dimensions shown. There has been some paper stretching over the years and some dimensions are not clear. I'm building a replica of the front portion and need some help with a few dimensions.
I've been working on making a CAD model of the gun. I need confirmation for several dimensions that seem close. Having someone that has one that I can exchange emails with would be a big help.
