What year was a Remington 41 cal derringer no 162 made?

Answer 1

Depends on the model, type, and variation.

There's three models, 5 types, and ?15 variations (have to count)

Additionally in some of these it wasn't even a serial number but a batch number since they started at 1 went to 9999 and then started back over again at 1. Really the best you can do with a double derringer it most cases is get it down to a small range of years except if it's one of the last models and some of the second to last and last type because that is because it's date code stamped on the lug since it was made in 1921 or later. These would all have UMC on top of the barrel starting in 1912.

The first place to start identifying which barrel is a picture of the writing on it, just what it says doesn't necessarily work since some variations are determined by type face or lower or upper characters or something as simple as a presence of a "."

You should probably visit the Remington Society of America on the web for more answers (or to ask more questions)
