The best I could find is HB-VAY 25135 which Richard burton bought for Liz in Sept 1967. the paint scheme matches. I suppose the picture could be a file photo but I'll ask around on Monday

For reasons I can't work out the photo doesn't always show but if you click Print preview it does?
If it was HB-VAY then it was a 3B and Written off in July 1970.
I'm actually slightly confused as G-INFO and other sources shows this as being constructed in 1969.
