Help on a Colt Derringer?
Digging around the basement I found a Colt Derringer mounted on a picture frame. I recall this hanging on the wall in our house when I was a kid in the 1950s-1960s. My Dad was a collector and partial to Colts.
The weapon is mounted on a frame of nice dark wood about a foot square on a red tweed matte. It has a plaque in brass stating "Genuine Colt Derringer 4"
It is a single shot and removing it from the frame indicates that it is chambered and marked for .22 Short. It also is marked "Colt's P.F.A Mfg. Co. Inc. Hartford, CT USA" The barrel is rifled and it breaks open not on top, but pivoting sideways to load a single shot. No Serial No. White or Ivory grips
Anyone have any info on this piece and how old it might be. I assumed for years that it was a replica. However, on taking it off the frame and cleaning it up, it appears to be a fairly well made firearm, like a Colt.
Any idea as to the mounting or why? Perhaps a dealer promotional piece? It does not look homemade, and the plaque is nicely engraved.
