1/24 - 1/25 Scale? The Opel Blitz kit Jeff showed is it. Well, the Mack AC kits would qualify as that design carried over into the '30s (from the '20s).
But otherwise, no kits.
There were a couple of resin kits a long, long time ago ~ All American Models and Herb Deeks both marketed a '30-'31 Ford AA chassis that was viable through the early '50s (with minor modifications for the 40s and 50s). Unfortunately, those are long gone.
