I may have the service manual on microfiche at work. Lemme check for you on Monday.
As for the motor, in the end bell of those Panasonic/National motors, there is a tiny circuit board with a pot, two or three resistors, a metal can transistor (2SB172 or 2SB324 IIRC), a disc cap, and a pot. The transistor will develop leakage and eat the pot or one of the resistors. The resistors are little grey colored things with no markings. Modern Mabuchi motors won't directly replace them - you'd probably be able to identify a motor that would work, but have to fashion a mount. MCM used to carry them - they may still. It's either a 6V or 9V motor, my bet is on 6V, fairly common back then. Most of the 6V motors were identical from product to product, just with different brass pulleys or idler shafts.
Somewhere I may have one, albeit without the circuit board...

Cheers,
