All I can find is "Address Sam Colt - New York City" and serial numbers on the .36, numbers in 4 places.
The .44 has stamped into it. "Colt Patent" and serial numbers.
On both weapons the serial numbers are just forward of the trigger guard and on the bottom heal of the gun. The .36 also has it's numbers on the cylinder. The .44 also has the letter "H" just behind the trigger guard. I'd expect that to be for Hartford, which is where Colt's company was located.

The dollar value is interesting but I'm under obligation to pass the weapons along within the family and tell the history of the weapons.

The Civil War pistols, Grandpa's Mouser from WWI, Dad's sword from Italy in WWII, and my SKS-56 are all part of family lore.

Stay healthy - thanks for the info,
Andy
