Found partially disassembled with schematic and other repair info, and a plastic bag with some screws and parts.  Did someone pass on before they got to it, or just gave up?

Body has some dings/scratches, but no cracks or breaks.

Real nice handle!  Thankfully, this version has on/off on the volume control, not the hinge, which was prone to problems.

Original price was about $43 - around  $550 in today's funds.
