Star Gauge Numbers on Early NM Rifles

[Tom Jackson]

Someone asked Rick if there were star-gauge numbers on the barrel of his 1915 NM rifle. I have not seen star-gauge numbers on any NM barrels manufactured prior to 1921. The star-gaue mark on the muzzle was added late in 1921. My 1920 NM (No. 1181306/SA 12-19) does not have the star-gauge number or mark. My 1921 NM (No. 1229240/SA 5-21) has a star-gauge number on the barrel but no muzzle marking. My 1922 NM (No. 1232141/SA 11-21) has both the star-gauge numbers on the barel and the star-gauge mark on the muzzle. My 1913 NM (No. 544856/SA 2-13) does not have any star-gauge numbers on the barrel. The star-gauge barrel numbers appear to have been added in Fiscal Year 1921 (July 1, 1920-June 30, 1921) and the star-gauge muzzle marking in FY 1922.
