ID these wheels and straight axle

These are from the trailer that carrys the Dunk Tank at the high school where me Dad used to work. I'm just curious as to what they're from. Anyone have any ideas?

 

I have a close up of the axle ends too, but it's kinda blurry.

 

The wheels look like General Jumbo's and the axle looks a lot like 1947-1955 Chevy/GMC

 

ditto on the Jumbo's avail. in 5 or 6 hole, I know of a six hole pr.Lot of chevys and dodges got em to get rid of those artillery wheels

 

I've p***ed up tons of those Chevy axles, because of the parallel leaf set-up, but I saw a car, last summer, with cut down Ford spring perches welded to square plates that were bolted to the axle, with the transverse spring over the axle.
It looked cool, safe, and makes great use of axles that, otherwise, get overlooked. Plus they have a nice drop.
