Looking for info on these super heavy duty 16” wheels

[Hastings]

Now since it’s getting dark out at 4:50, Ive been beginning to organize my summer horde. I can’t seem to find anything that would have used these 16” wheels. I originally thought cycle truck but from my understanding these were all 20”. Both are front wheels, both bendix with chain tires. Any comments or info is appreciated! Thanks!

Bound to be cart wheels. Could very possibly be to one of those sweet looking icecream trikes though.

I imagine they don't have any knurling or stamps that indicate Schwinn, right? Worksman of that age would probably still be drop centers I imagine.... I don't know any makers names of the cargo/cooler trikes from right around 1950, but I think that's the era of those hubs. Tires with that round "US" stamp might date to early post war...?
