Steve,
I have a couple of other candidates for your list of pinfire makers.
My wife’s Uncle has a pin fire gun marked “S. Leech and Son” on the lock plates and “G.T. Bartram, Braintree “ on the top rib.
The action and Barrels bear a single set of 13 bore 1855 to 1868 Birmingham proof marks.
I had always assumed it was built as a pinfire by Leech (Leach/ Leetch - they seem to have been undecided on the spelling for a while) of Chelmsford but re-barrelled by Bartram.
Thinking about it , given the very short number of years that pinfires were in demand, it occurs to me that it may have been converted from a Leech muzzle loader by Bartram.
It has a one piece iron butt plate, as you would expect on a muzzle loader, and the pinfire barrels show signs of much use, but not a lot of cleaning.
Leech were certainly building guns in the muzzle loading era, and it seems Bartram were in business earlier than Nigel Brown’s book suggests.
I will try to post some more images,
Keep Well
