Vintage Swedish Army OD Green Work Shirt Military Cotton Field Uniform Olive 40

I'm not 100% certain, but believe this is a vintage Swedish military shirt. Hard to see, but it's tamped 1967. Shirt is wrinkly, could use a good washing and ironing. There is a small blue mark on one of the pockets (looks like paint). I did not wash at all. Looks like the size tag says size 40. Not sure what that translates in US size. Here are the measurements: Armpit to armpit: 21 inches Sleeve length: 24 inches Collar to bottom of shirt: 29 inches ~ New to Poshmark?
