hub cap identification
 

I was given a set of hub caps from my uncle who aquired them around 1960. Alot of people have looked at them but no one has convinced me they know what they are talking about. Need someone who really knows what they are talking about. I would like to post a picture but have been unsuccessful in doing so. The hubs have a two blade spinner or knokoff with two different flags, and the inside of the center is copper, which is visable from the inside of the hub cap. There is a design in the copper, but I really can't tell what it is. If you will respond I will e-mail pictures to anyone who can help me.
