What are these wheels? Are they period correct on a '75 and are they worth anything?

Finally, where's my best source for a nice set of Fuchs? Thanks!

Westerner? wheels I think? Worth something, I think they are a decent wheel.

By fuch you mean the 4 lug 2.0 Fuch?

They were sold under several names, Western, Shelby, American Racing. I had a set of American Racing on my 914. Plastic center caps are rare to find now.

Here's a shot of mine from about 1980.

That is an imitation of a 'Gurney' wheel.
Were popular and have 'period ' value and appeal

I will have a set that I'm going to be looking to get rid of in the next week or so. You're welcome to them for free if you want. Just pay for shipping.
They aren't perfect but they can be cleaned up.
