I will sandblast the rim the next time I am out at the barn, and will also photograph the results.

So, what the hell is a KH wheel??

I admit, my first thought when seeing the bolts was that someone had broken or damaged a couple of adjacent studs and taken the lot out and replaced them with SAE thread bolts (this only really makes sense if the HUP series used the same Whitworth fine thread wheel half joining studs as 15 cwt (and 30 cwt?), 60 cwt are mushroom headed instead of flat headed).

KH = Kelsey-Hayes, maker of wheels and possibly other chassis parts.
