Technical Can somebody tell me who made these wheels?

I have several sets - often referred to as “Composite Wheels” due to the different materials. One set was on my ‘37 since I was a kid (I took posession of the car in ‘18). Car sat forever outside. Long story short; had all the wheels checked after new tires wouldn’t balance; all of them bent / out of round. 14s, 15s - didn’t matter. Had to spring for brandy new ET wheels to get the look / size / backspace I needed. None of them had any markings.

 

The Keystones had the K logo between the lug nuts on the back. Maybe if OP cleans up some of the cobwebs you'll see some small marking in that area?

 

Look like a '60s Appliance wheel

That fat/flat rim lip on the front side isn't like any of the name brand wheels I've seen, most of them have a nice thin lip (even the Appliances). Probably cheaper store brand knockoffs as suggested.

 

No …. I don’t believe they ever welded a cover on a steel wheel.
I do remember these but not the brand. They were cheaper subs***ute and heavier than the all aluminum ones…
