"I met up with David Sanderson recently. He bought my silver (original colour) 1969 428 Fastback CF 19 from me in the late '70s. Its registration number is OOK 50 G. David ran it for some years, did his usual superb job of respraying it, this time metalic blue, and then it was sold to the US where it remains to this day.
I looked through some old photos of the car with him - these taken in the US and hence, I assume, why the knock on wheel spinners have been replaced with the 'safety' items. We were reminded that some Fastbacks had a small 'Frua' badge behind the petrol cap covers, rather than the usual small 'AC' item.
I don't think CF 19 was unique in this, but I don't recall many other cars being so fitted?
