Hi Letfly
nothing too unusual about the standing breech. Thought you meant it was split horizontally and in two sections.
Judging by the way the hammers sit at the nipples, something ain't right as they should hit the cap squarely. I would agree that these are probably not the original hammers, and there may well have been some doctoring to the flash guards to allow these hammers to function on this gun.
can't offer any more i'm afraid. enjoy shooting it, but keep an eye on the wood behind the breech....
