Here she is
Rail voltages seem good, from the meter.
A couple of things I notice
1) when the power is turned on, it moves forwards (always forwards). No amount of cycling the button will restart it, once stopped.
2) there is a longitudinal (fore-and-aft) slot in the top of the body shell. There are no other slots in the body. I assume this is for the reversing unit, which is lost?
