I have just spoken with him, and he gave me a run down on the 41 which was actually a 41Bbrought out here as a test car. Alex bought it from MacLean(?) in Napier (who had crashed a Tiger Moth) and then turned into a Formula Ford. Alex put a new body on it after a biff or two, put the side rads on (and a new chassis) sold it to Kevin Ingram who won the Champs in it, Bruce Turnbull helped him rebuild it into the car which is around. Probably the only bit still around from the original car is the (illegal) gearbox.
Bruce Turnbull also got the U2 and it wound up with someone in broadcasting who apparently still has it.
