Mike Boulware is quite knowledgeable about lap steeles. If he can't help you he can point you toward someone who can. He's a real nice guy and a good friend. Tell him John from the 24th Street Klezmer band sent you.
Kalamazoo guitars were made br Gibson in h 30's. They were not seconds but were a separate, lower priced line. Kinda like Ford and Mercury.
