I happened to find this 16mm film of the Kiwis and their Vincent several years ago. It was in fair shape so I had a company restore it and put it on a dvd.
In 2005, I located this same Vincent in my neighborhood, almost 50 years from the world record setting date.
The owner graciously arranged for Russel Wright and wife to attend a very special 50th anniversary reunion of the rider and his machine. Russel in turn, presented the owner with the trophy given him for setting the land speed record. About 300 friends and fans came to celebrate the event.
