Is this the Grade 4 that was in the last Rock Island Auction ?

Yes. It is a very interesting gun in that very few grade 4 TL hammer guns were made in either Damascus or Bernard ( like 100 total). I am very seriously considering doing some restoration, but need to have Brian evaluate it mechanically. The barrels are very sound, the stock is sound and untouched. I'm thinking about a barrel finish, recut checkering and a new bolt.

I was at a gun local show Sunday and saw a 10Ga Parker hammer with a flat plain rib as well. That is what caught my attention. It had a round grip, splinter forearm, top lever and semi loose lock-up. The butt plate was plastic with horizontal lines (the screw heads were still timed). The Damascus barrels were brown and hard to see the twist, bores appeared dirty so I couldn't determine their condition. The owner had it marked for $680.00 and offered it to me for $525.00 after seeing me looking at it for a long time. I might have been the only guy there that showed any interest in it.
