Thanks for that, I also asked Tim in Ca to have a look at his
utilities panel, but he went up on the roof and checked the fan motors
on the aircon!  460V Nominal, range of operation 440 to 480V 60Hz. The
charger will be OK on 440V 50Hz and 460V 60Hz, running slightly cooler
on the higher frequency as usual.

It was the AV1 and the AVA1 engines, originally sold by Kirloskar as
agents for Petters, then they started making them themselves when the
licencing agreement ran out. Same with the Lister engines but a
different agency handled them.

AV1 was water-cooled, AVA1 was aircooled.
