Thanks Jent. I haven't take it apart yet, but the only stamps on it are the proofmarks, not for ball, and 10B, 11M. On the watertable the A&D use number is stamped in a curve on top with Anson and Deeley's underneath. Patent is curved the other way below that to make an oval shape. It doesn't even have a serial number.
edit, Yes the breech balls are slightly proud of the barrels. I've seen a Dickson that was also that way.
