Check out the "Drummers guide to Vintage Drums" by John Aldridge.
He also has a website and magazine "Not so Modern Drummer Magazine."

The website has a forum, perhaps you could post there.
If you like, I could email John your photos, and he would be happy to give you a realistic idea about what they are and how valuable. He's a good guy.
