Other companies including Rock Island Arsenal, International Harvester, and Harrington and Richardson also produced M1s but we do not have the breakdown for these firearms. Note whether the arm was produced by Springfield Armory or Winchester Repeating Arms Company before looking at serial numbers. The serial number listed is the last one produced in the month all given serial numbers are approximate.
