Help Id on some wheels

So I was messing around in my neighbors junk yard and I saw these wheels. Thought they were interesting. Any one know what theyre off of? The one with the chevy hub cap is on a divco, its a 15, is this the wheel everyone is always looking for?

 

The middle one is '30-'31 Model A Ford 19", the one on the right with the 6 lug pattern is early '30s Chevy. Is the Chevy wire wheel 16 or 17"? That would narrow down the year(s). The one on the Divco looks to me like a late '40s/early '50s Chevy pickup wheel, doesn't look like the "milk truck" wheels that are sought after. Don't know what bolt pattern Divcos had, so I can't say whether that's a Chevy pickup wheel or just a wheel that the Chevy cap fits.

 

first one is a steel split wheel , second model a ford wire , third chevy wire probaly 17 incher

 

Are they worth anything or just neat looking?
The wheel with the chevy hubcap, the back wheel on the same side has an International cap. He used to use the truck as a camper and now it just sits.

 

I'd just leave those Chevy mankillers alone. Way too much work for something very few want. Jay

 

Center wheel os a 28-29 Model A Ford takes a 21 inch tire. Rolled rims rot out. The one on the Right may be a 1933 Chevy item. Bob
