From memory, this was the one that stopped charging halfway home at Newcastle (idiot light came on). NRMA played with the cutout contacts, resulting in magic smoke coming out of the generator (whilst the engine was off).

Yep. But I think the damage was done before Mr NRMA pushed the cutout relay contacts shut. There was a lot of thrown solder from the comm. inside the generator, suggesting to me that the generator had been overloaded for a good while.

Another useless piece of generator trivia: English-made C40 generators have the same distance between mounting holes as C39s - the yoke is 5-11/16" long. The Australian-made C40s, in contrast, are about 3/8" longer. The yoke is 6-1/16" long.

Funny that - I wondered why the two dead armatures, one C39, one C40, looked just about identical in dimensions.
