You may look at the Vehicles of Victory website, a site dedicated to Chevy and GMC WW 2 trucks. If you have a real tractor, it would be rare as not many were built. Since it is already in Europe, provinance could be that it worked the Red Ball Express! From my knowledge, Chevy trucks never had serial number frame stamps. If it has one, it is most likely mandated by some municipality where it once "lived" post war.
The timkin axle is not correct though as all of the Chevy's had what was called a "banjo" differential. It think it is an easy swap from the early GMC CCKW which did use the timkin axle. CCKW's did have serial numbers stamped on the frame. Are you sure it is not a "bobbed" 2 1/2 ton GMC truck? A lot of things happen over a 71 year period.
