Thanks for the info - this is all new to me. So if it has repair marks of July 1922 / 1928 how do I determine when it was originally made? is there any way to source an appropriate butt plate? I'm thinking of having it cleaned up/restored a bit then display as a decorative piece as I just like the way it looks, have enough other functional guns for shooting/hunting. At some point the firing pin for the rifle section was removed, don't know how or if I could get that fixed. Last question is what if anything is it worth? Need to know if I should list it as a valuable item on the insurance, it's true value is just nostalgia for me and something I'll pass down to my boys.
