The autopilot system as a whole does not work but the drive motor appears to be OK. Since I don't have a way to test it, I'll make a deal. I'm asking $200 for the motor. If you want it, I will ship it to you at your cost. If it works for you, you pay me the $200. If it doesn't work, junk it and you are only out the shipping.
Here's the whole setup. The drive motor is the lower right hand component.

Here's a closeup of the data plate on the drive case
