I think it was re-bored in the past 5 years. The rifling looks like they came from the factory, in fact the entire rifle looks like it walk out of Bond street yesterday. George Caswell as also completely guaranteed it, even to the point of re-regulating the barrels to my load free of charge.

I see H&H are making round body back action rifles/shotguns again. Looks like the old Dominion Grade.
