mcdhu, Ian, I have a photo I took of you beside a C150 and one someone (possibly you) took of me. I would post them but I seem to be not permitted to post attachments on this forum. Don't know why ...... anyway, I'm impressed by your powers of recall. Was Richardson the guy who rode about on a motor scooter wearing an RAF bone dome which had the legend "Haggis" written on it ? However, I think there may have been seven to begin with. ...... the six you've identified plus the Sea Cadet. He wasn't Richardson, he wasn't the man with mini-bus and he wasn't the guy who left early ?
Happy Days !
Chris
