This was borrowed from Fred Crismon's excellent
"US MILITARY WHEELED VEHICLES"
At first glance it doesn't look that similar, but if you swap the shortened cargo body and winch for a longer one and give it a hard cab.... Note the long hood nameplate too.
Unfortunately the 1934 manual appears typed ( not even printed or lithographed or whatever) and does not contain the list of USA numbers that you would expect on any later military contract.
