Simeon North 1822 percussion with Octagon Barrel? I *think* it is an U.S. Model 1819 Flintlock Pistol converted to percussion. But I do not know antique firearms. On the Right side behind the hammer it says "1822" In front of the hammer (covered slightly when down) it has "S.NORTH." on a downward curve over an Eagle and Shield motif. The Eagle/Shield flanked on one side by "U" and on the other by "S". "MIDLTN CONN." is stamped in an upward curve below the eagle. On the right side about an inch front of the metal, it looks like an 1/8th wide of an inch cut has been filled in by a wood piece. (Looks like it was where the metal spring was that held a barrel band). On the left side "LS" in an oval behind the side plate. The barrel seems to be about 11 1/8 inches long. The first 4 1/2" is octagonal, the remaining barrel is round. It looks to have 7 grooves in the bore, I can't tell if it is rifled. Seems about 3/8th inch bore. One flat section left of the top of the barrel across from the percussion nipple is "V" with a line under it and then a "P" under that. One flat section left of that and a bit forward is an "R" So, am I correct that this is a U.S. Model 1819 Flintlock Pistol converted to percussion? And that during the conversion the lower part of the frame was cut down and the metal spring section filled. And that the barrel was changed over? Was 1822 the date of manufacture? Any idea who and when the conversion was done? Any idea on value?
