Crumar Musical Instruments User Group.

Does anyone have information about a CordMagicVox Piano Accordion with a Crumar Tone Generator which connect with each other through a Thick multicore cable. There are 3 sets of ITT Cannon D Connectors on end of thick cable.

I believe the Accordion was made by Crucenelli.
I know that the Tone Generator was made by Crumar in 1976. But Crumar went out of Business in the Mid 1980's.

Any user manuals, service manuals, schematic diagrams and other info will help with restoration & playing this wonderful Instrument.

Thanks,
Al
