Re: colt revolver
Hi cdixon......welcome to TFF.
Your description of your two Colt revolvers is somewhat confusing. The Colt Army & Navy cap and ball revolvers had the roll engraved naval scene on their cylinders......but they were made long before the .38 Special cartridge was invented, and, as far as I know, none were ever converted to that cartridge. Further, no Colt revolver ever offered in .38 Special had that scene engraved on it at the factory.
Can you post photos of your two revolvers?
Also, give us all of the writing on them, exactly as it appears, and where it appears.
