I've been known to make mistakes too, Eric, but I'm bettin, without being argumentative as well, you'll never find any documentation of any such thing - the one Tim links is just like the one Dusty built .... homemade, patterned on old style horse drawn freight buggys
and I'd bet there were quite a few similar built by farmers on 3/4 and 1T pu's back in the day for carrying grain to the bins, farmers who couldn't afford a 1.5/2T flatdeck to do the job
