Thanks guys! There are no marks on the business end and there is a 1/4 inch "dent' smush on the other side that disqualifies it from being pristine. Plus the nickle size discoloration seen in 2nd photo.
There was also a .56 -.56 Spencer rimfire in the box in nice shape. I asked about that on TFL a couple years ago.
I hate to ask, but since I'm not a collector of this stuff... What would be a fair value? I'd like to let someone else who appreciates it get it. (Likely in trade for modern HG ammo if that's fair.)
Edit to add.. I googled around and can't find a value.
