Hi Roger,
I've been told we have 8 in New Zealand, 2 in Auckland (I've been for a drive in one which was a 1930 coupe), 2 in Taranaki (1 is a ex vintage racecar out of Aussie and my 29 130), 1 in Southwards museum and one in the South Island, I cant re-call where the other 2 were but the guy who told me was sure there are 8.
He also seemed to think the Auckland coupe was the only one in going condition, hoping mine will be the second one early next year, wont be pretty but will be drivable.
Neil
