The only standard mark throughout the doulbe is the X and an O but we believe the O to be a marker indicating right from left as the O only appears on the left side parts lock, breech, etc.
On further inspect I have found the initials J? M B I beleive the first letter to be J the M,and B are quite pernounced. But this may only indicate the maker of the butt plate as it was found on the inside of the mechanical patchbox, on the butt plate, I am very thankful for all info this is all very helpful into identifying this peice of history and whether or not it needs to be preserved or reworked... Thanks Again A.J. Downey
