Damaged carbine

[Edward Tinker]

Well Tom says he has a 9mm Martz, with rear sights already - I assume its a short frame barrel, I couldn't tell if I was looking at it.
GT says he could probably work it either way.
Eugene says he can make me an exact replica, I just don't want it to cost $2500 and I get it back in 2 years....

Measuring the barrel tenon is the way to tell long or short action requirements.

If one looks at early long framed navy's on Simpsons site, say early 1906's versus later 4" navies on same site.............looking at the frame curvature just in front of the takedown pivot might infer that yours is a long version. Purely conjecture from here, measuring is the absolute way; I am sure G.T. has a depth mic.

The 2mm difference is about a turn and a half on said barrel threading, so if one got a short barrel for a long frame; the shoulder would have to support said modification(set back).

I appreciate seeing the attachment of the forearm hanger, something for me to save off as a piece of knowledge. Also thanks for the general posting of your new acquisition.

The frame is assuredly a long version, it is an original Old Model carbine.

I would appreciate it if someone could authoritatively post the precise barrel threading difference between a short and long receiver.

The forearm hanger is originally only soldered to the front of the frame. The screw attachment on Ed's carbine is an owner modification.

Well, yes and no. Production carbines had only a soldered connection of the forearm hanger to the frame, but originally on the very first prototype carbines the hanger actually employed a screw as well as solder to affix it to the frame.

I'm not sure what you want to know "precisely" about the threading difference; but there is an long frame old model drawing in Goertz and Sturgess around page 1740 in the red books, and the short chamber drawing is readily available. The length of the barrel that extends into the receiver is 21 mm on the long frame and 19mm on the short frame.
