Those things wreak all sorts of nostalgia!
They do, that's one of the reasons I want to take it hunting. I don't imagine this thing has bee fired in 75 or more years but wouldn't it be cool to get a few full brass shells and load them up.
I might be able to help you out with that....what is the gauge? 12ga.?
