I wonder why no one has bid on it? Probably scared of the Damascus barrels. If there are no signs of pitting I would load up some more brass 12ga shells with black powder and enjoy the heck out of it.
Back when I was competing in CAS I had a Damascus double hammer gun by Stevens. I shot it for 10+ years with nothing but black. Never a sign of problem and it locked up as tight after all those years as when I bought it in the pawn shop.
