Sorry, Hatfield 125 is only my user name, I'm Chris Bonass and worked in various BAe photo/film units, initially at Army Weapons, Stevenage then Civil Aircraft at Weybridge and Hatfield.
I'll post details once I've finalised the how and why of digitising the films. Unfortunately, the Tiger Moth video is not one of mine so I can't help with that production.
