Oldfart, we meet again, the BSA Special, yes I would love to know, where it and the owner are - he may still have it. It was never mine but did drive it often, including at a Sprint meeting on the main Pukekohe circuit once as well as in Gymkhana's and on the road.
Here is a photo with Lyle Chambers driving and his best mate Richard Leaper [ Flying Officer J R Leaper as was in the RNZAF at one time ], the car is pulling into the driveway at my house in mid 1970's probably around 1976.
I have more of these small photo's, hopefully someone may recognise the car and the owner..
