Q. My great grandfather carried this Colt swing-open derringer for years. Under the handle, it is plated silver or something. It seems to be a rimfire with a .44-caliber rifled barrel. It is marked “COLT” on top of barrel. Is this a real Colt or a reproduction?

A. From your photos and description, I believe you have a Colt 3rd Model Derringer, sometimes called the “Thuer Model” Derringer. These were made from 1870 to 1912, with about 48,000 produced. They were all chambered for the .41 Rimfire cartridge. I think yours is most likely an original Colt, as I don’t believe any other firms were producing anything exactly like this model during that time frame; especially not with the typical “COLT”-marked barrel you describe.

With a serial number of 3450, your Colt was probably manufactured fairly early, although the exact production dates by serial number are not known.
