I came into a Richardson conversion of a second generation Colt Model 1860 revolver and a Richardson-Mason conversion of a Colt Model 1861 revolver. The conversion work was done by a gunsmith in the Denver area. I am unable to determine who did the conversion because the previous owner took this information to his grave. The conversion work is excellent but the cylinders lack the engraved scenes. I understand that there is someone out there that has the capablility to roll engrave the scenes on my cylinders. Anyone know anything about this?
