Bill,
I am the UK-based AC Owners' Club Cobra registrar, and am researching a couple of 2151 points. I'd be grateful if you would email me with your contact details so we could have a brief discussion. I spoke to Kevin Kivlochan last night, but he hasn't kept his records of eleven years ago.
Kind regards
