I sold the gun to a fellow in PA. Actually, it originally came from the Hamburg Gun Library. Saw it there when I was passing through PA, had it sent back to Owatonna for a 2nd look, ended up buying it.

Chief, I believe the subsequent owner shortened it, because that LOP would be too short for me too. The drop would've worked OK.

Dave, if it's a 60's or 70's gun, which I expect it is, the date code would be a small case letter, in script, underlined. They can be a bit harder to find on OU's sometimes than on sxs. Does yours have a one-piece forend like the gun in the photo? Sometimes on OU's with 3 piece forends, proofmarks are hidden under the wood that you don't detach when taking the gun apart.
