Hi Gang: Another treasure..... It's new old stock in the box. Model is 5300 6 Volt vibrator. Was probably used for a car radio in the 40s or 50s. The base diagram is A. Anyone need it? I sure don't. $7.00 plus postage. If interested please reply by e-mail. Cordially, Michael Crestohl, W1RC mc at sover.net Cordially, Michael Crestohl mc at sover.net
