I just bought a "fine twist" double muzzloading shotgun.
I took off the barrels and the following proof marks are present:
The E over LG in an oval - star is solid.
178 - Pretty sure this means 17.8mm, which is 0.700in, which is what the muzzle measures, so a 14ga?
The "Perron" - on the outside of one of the chambers, visible while in the stock.
Reverse "B" "L" - made after 1852?
Crown over V - on one chamber
Crown over G - on one chamber
Crown over GI - on one chamber
Crown over X - on the breech block on both sides
"JM" - stamped on one barrel, covered by the stock, a makers mark I believe but cannot find anything to line up this mark.
Trying to figure out who made it and when.
Thanks
