I finally decided to check the only 1932 Izhevsk I have. It has a low serial #444 and all numbers match. It has the hex receiver and the sight base looks like the one in message #1 with the kind of squared base leaving a small gap. It is not rounded and close fitted like the one in message #2. It is also in a laminated stock. Yes, I know you want pictures. I will have to see what I can do about that. I don't have a camera or a cell phone with a camera.
Okay, I got two pictures. Maybe they will show up.......................maybe not.
So a gap at the back of the sight base means it's an ex-Dragoon? I don't have a 1932 M91/30 but I do have a 1931 Izhevsk and it has that gap! Thanks for the info. I always wondered if it might have been a Dragoon!
I think it may be hasty to assume that just because the gap is there, it started as a Dragoon with the 1930's 91/30 rifles. Although that is a possibly, they may have been using up what materials were on hand to complete rifles.
