Interesting. So the vehicle was a '46 design, built in '47, but sold by Chevrolet as a '46.
Well... it's technically a GMC (not a Chevy - but same diff, right?). Pretty much when WWII hit, all manufacturing was for the war effort (well, except farming and a few other essentials). Consumer vehicles didn't change from about 1941 till around 1946 +/- (till they got the manufacturing lines re-jigged; that and some are left-overs from military surplus).
It's a fascinating period of time. Even pennies were made in steel for a period (1943) - the copper was needed for the war effort.
