Neil,
Yes, I am referring to the electric motors rather tha the generator.
I have not seen (to my knowledge) a generator in Australia, but there is a good article on them by Kim Siddorn at
http://www.wessex-sec.co.uk/2007%20N...rs/Jul07p2.pdf
There is a good often published picture of a Kerrison aimed Bofor battery in the south of England waiting for V1s. There may be a glimpse of the generator in that - I will have a look and see if there is a better picture reference in case you do not know the picture I mean.
cheers,
Damien
