I was about to post and say it was CF68 and found m'learned colleague had beaten me to it. Just checked this in the 428 registry in this webbysite and I note that the registration number, 5ALD, has missed its alloted box and been entered against CF69, which I know is the Tony Valenti hot-rod (hi Tony) so maybe some responsible official will read these pearls of wisdom and make the necessary correction?
428s to 'Cobra', that I'm aware of: CFs 23, 35, 39, 47 plus 68, of course. Methinks one or two others have been cut n shut but I can't quote numbers.
