 What, no 40 hp MG set generating 400 Hz 3-phase? :)

No but it was run off a world war two air ministry (diesel) engine  
driven generator for a few years. The generator was a 1700 cc twin  
cylinder unit with hand start and a flywheel weighing several hundred  
pounds. I had to keep fit to get that to start on a cold winters  
morning when the oil was thick and the cylinders were cold.
