Took it to bits today, and it is bits.
The 3 securing posts on the generator were all broken off and had been crudely glued.
There should be 3 brass washers between the case and the generator on the bolts, there was only one, the other 2 had been put under the movement.
The movement is free running but there was a lot of slack in the bearings. The bottom one is spring loaded but the slackness allowed some sideways movement. I adjusted the top screw gently and it allowed more free movement of the rotor towards the infinite end of the scale.
The 5 pieces broken off the generator and the main body were scraped free of the nasty glue, washed in acetone and the whole put back together with super glue.
The capacitor just about passed muster, a bit of leakage at 200v, the resistor is within spec, the 3 coils OK, so the whole was reassembled.
It now flies to short circuit and makes it more sedately to the infinite end, so it will be OK.
