It was a seminal source on Gas Trap research back in the early 1980s... I examined it at the invitation of Herb Woodend, the guy in charge back then shortly after they moved the collection from London to Nottingham. We were on the way to visit our daughter in Johannesburg and could not fly direct because of the boycott. Took the Concorde, what a hoot... on the way home we arrived in NY 30 minutes before we left London![]()
