Hubcap identification

[Johns66]

I need help identifying a hubcap it measures 10 1/8 from edge to edge of the inside lip.

The wheel it was on measures 16 1/2" edge to edge.

There is some rust on the backside so I do not see any markings.

Pictures are below any help in identifying is appreciated.

Good information, I am going to try to sell them as I want to raise money to put an automatic in my truck.
