date of sale rather than YOM was the standard until into the mid 50's, if the title says '45 then it's a "1945", but what's in a name?
the 42-45's were all the same continuous production, there wasn't any real change from 41 except a few assembly line "running changes" - truck production didn't resume until mid-45, and the trucks produced then were just 41's rushed to market until they could regroup
