Looking for info and value on this gun. I have read a bit but cannot figure out much other than it seems to be an 1886 10gauge.
The Lug is marked with what looks like js and o2. even appears to be a partial 7 that is wore off behind the two.
Where the grade should be all I am finding is circle T 5 and a serial #. Nothing more. Any help appreciated. It belonged to a friend of the family who just passed. Had been in his family for generations.
