This is an early cartridge Colt that was factory converted from a Model 1862 Pocket Navy Percussion Revolver to .38 rimfire. Serial number is in the 790 range with all matching numbers including grips...as well as sub-assembly numbers on the loading port, inside the frame and arbor pin. It still has its original 1862 Navy octagon 4-1/2" barrel making this one of the slightly scarcer Conversion variants of the Models 1862 Navy and 1862 Police. Flayderman's Guide notes this type...the Navy Model with 4-1/2" barrel was made from 1873-75 with a total of 2,000 units. Colt 1871 and 1872 patent dates located on the left side of the frame. Barrel is marked: ADDRESS COL. SAML COLT NEW-YORK US AMERICA (see photo). The cylinder has 95% of its orignal scene present...quite good.
Overall NRA Antique Good+ to Very Good Condition. Metal has worn to silver with traces of original finish in protected areas. Nice markings throughout including a super cylinder scene depicting a stage coach robbery scene (see photos). The action is in good working order with a Very Good Bore. Grips are original and numbered to the gun. The original walnut shows 20-25% original varnish remaining. Solid but show plenty of wear. Fair+ Good condition overall with numerous handling marks...a couple of tiny chips in the corners. Solid with now cracks. A good solid representative of an early Colt Conversion Revolver that's 100% original down to the smallest screw.
