I'm going to come at this from a slightly different angle, but I'm a Military Vehicle collector and restorer. My White Scout Car and Halftrack material indicates that Cletrac was a White subsidiary and the rear tracked drives and tracks for the halftracks were developed and supplied by Cletrac. To keep up with production Diamond T and Auto Car also built halftracks and used Cletrac drives. International Harvestor also built halftracks, but I do not know if they made their own drives or not. i guess in 1944 Cletrac went to Oliver. Oliver later acquirred Minnepolis Moline and then White ended up with everything. I'm a little fuzzy on the dates, but My uncle was a longtime Moline employee and when they merged with White he lost all his pension and retirement benefits., It looks like Cletrac has been involved in a full circle of changes and with White on a couple of occasions. The M2 military cletrac used a rubber track similar to the halftrack, but the halftrack pads were not replaceable. I've learned a lot in the forum that I joined as I ended up with an M2 Cletrac in a deal for some Scout Car Parts. Thanks Howard in ID
I owned a white halftrack as well and it was my understanding that b.f. goodrich developed and manufactured the endless rubber track. i had an n.o.s. spare track that was clearly marked as such and the tracks that were on the vehicle were marked that way as well. i can't say who developed the boggie system on the suspension but i thought the engineers at white truck did.
