Stevens 12 gauge single shot
I have an old Stevens Single shot 12 ga. that belonged to my father. It has plastic butt & forarm with a place in the end of stock to unscrew and add sand or something I suppose to add weight. only # I can find on it is 10 the blueing is pretty much gone. there is a patent # on stock but I can't make it out. Gun still shoots great! and is a great shooting match. Whats it worth & how old is it?
