1942 winchester m1 garand
hello everyone, new to the site and fairly new to milsurps. i have a swedish mauser 6.5x55, no.1 mk3 enfield .303 brit and an m1 garand 30-06. the question i have is about the m1, grandpa always told me it was a national match rifle but the only part i find stamped with the "nm" is the charging handle. it is a winchester, s/n is 1.2 mil. july of 42 best i can tell. It appears they didnt make national match m1's until after the war but im not sure, just my attempt at a google answer, lol. any help on the subject would be appreciated.
