Anyone know a good place to get information about a vintage electric guitar that has no identifying marks?

I bought this used in 1980 by my uncle who was singing in bars in northern Michigan. It is completely original and mint, to see yet another Les Paul copy that looks like this one.

You may want to take you to a local guitar luthier "repair shop" They should be able to talk about his guitar, or refer you to someone who knows.
