Hi all, Ive been a member for awhile, but it as been quite some time since Ive been on. I bought a 44 flat top in Tulsa Saturday. Barrel has been cut down, but I like it! My question is, what base pin does it use? Does it share this part with any other models? It has a funny looking base pin (not a Belt Mtn) with a spring loaded pin in the end. I assume it is an aftermarket New Model.
