I am by no means a gun expert, a customer of mine husband passed away & i went over to take a look at some of his guns she was going to sell & this one was in his collection. took the arbor for 30 cal out of my bore sighter & it was loose in the barrel but the 32 cal would not fit. anyone have any input on what it is? there is no caliber or manufacturer on the barrel, stock looks to be off another gun as it has been all glass bedded. real pretty wood on the stock. oil left too long on metal though.
