When the new sight was retrofitted to some overhauled carbines, it could obscure all or part of the original serial number. One of these new components was the improved rear sight that was fully adjustable for windage and elevation.

When they were arsenal rebuilt after World War II, regulations called for any superseded parts to be removed and updated components installed. Can you explain why the serial number was stamped on the gun twice?Ī: Most M1 carbines were originally fitted with non-adjustable "L-type" rear sights. The two serial numbers appear to have been stamped at different times. The only unusual aspect of the gun is that it has a serial number in the normal location (behind the rear sight), but the same serial number is also stamped in front of the rear sight. The data in the following table were adapted from Brophy (1977).Q: I recently purchased a "G.I." M1 carbine.

Smith Gun Company (1946-50) started with FWS1 and ended with FWS 56800. Others have the suffix “R” (on both regular and featherweight frames). Adding to the confusion is that some pre-1913 ejector guns have an “E” at the end of the number, while others do not. Starting in 1917, serial numbers of all types, gauges, and grades are intermixed. During the period of 1890 to 1916, many numbers are not sequential with blocks of overlapping numbers assigned to different types of shotguns, such as hammerless ejector guns. SERIAL NUMBER DATA BEFORE 1890 ARE NOT AVAILABLE. Smith serial numbers, as they are related to year of manufacture, are confusing.
