This is from the 1969 RAF Leuchars Airshow. The slide quality really goes downhill here, but I hope it's still of some interest. Ironically these ones are actually Kodachrome, which I'd have thought would have survived better than the earlier stuff, which I think was Perutz:
Would you happen to have an old 1969 Leuchars Flying Programme. I'm looking to update/revise one of my books and the 1969 Leuchars programme is one which is notoriously difficult to track down.
