Hi,I was at an estate sale this weekend and seen this rifle in a wooden box.It was in two peices and had never been removed.When I saw it the pretty wood caught my eye but I thought it was one of them 2 piece kentucky style rifles.It auctioned for 75.00.When I got it home and removed the blockes and took it out it has two barrels,like a over under but only one lock.The only thing I found in the crate with it was two targets with three holes in each one with a note that says (sighted in each barrel at 50 yards Lorence)Does anybody know how to attache the barrels to the stock and what have I got here.Thanks.
