Capitol Music Inc. - became production manager at Batavia Metal
Products Inc. in Illinois (parent company of Challenge), and then of course deeply involved in the
production and design of the Filben Maestro and also the Challenger 47.

Batavia had stopped due to the patent disputes between Rock-Ola and Batavia
(he was fed up with the phonograph business).
