Rare Desco Dupliscaler - Parts Or Repair

For consideration is a rare Dupliscaler by Desco. The set comes with a working motor and a sharp needle. Overall, it looks to be in good used condition. All joint parts are move freely and no sign of stuck. Given our lack of knowledge, unit is untested and offering "as is" and as described.

Pls view all attached pics as I am not sure if any parts is missing. Unit will come with original manual and attached wires.
