Metropolitan Navy Revolver

Nice example of the Civil War Metropolitan Arms Co. Navy Model Revolver. These were very close copies of the the M1851 Colt Model Navy Revolvers & were mfrd when Colt factory had some serious fire damage in 1864. These are single action, 6 shot .36 cal. percussion  revolvers with 7 1/2" oct. barrels. One piece walnut grips. Revolvers are 13" overall length. This Metro has all matching serial nos. 6193 including the wedge. Only traces of the cylinder scene are intact & has the serial no. Metal is smooth with gray patina & brass has a mellow patina.  Top of barrel is marked with <Metropolitan Arms Co. New-York>. Walnut grips in good used condition. These Metropolitans are considered by collectors as a secondary Martial handgun. This one has some unusual stamps on the inside of trigger guard & on the butt, (H.T.C.C.H.} Been trying to figure what this stands for. Nice example of a Civil War Metropolitan navy revolver.
