The mixed number US gun is commonly known as a "artillery" model and is probably correct in this configuration.First I want to say I know absolutely nothing about single actions but I am trying to help a friend liquidate an estate and he has three single actions. One of the has a stamp that says US on the right side of the frame. Its serial number is 18890 on the frame and 34236 with J.T.C. stamped above it.
The second serial number is 819080
The third is 207275 which I believe has been refinished in nickel
Any info on these would be helpful
The nickel gun has been refinished and was mfg in 1901. The pearls are nice.
The 319 gun was mfg in 1911 and from the pics looks correct.
