I think I looked at the right video. That is a nice looking combination lock. Looks to be a 4 wheel Yale? Please correct me on the brand
The video after that seems to be of a Chubb change-key lock. Did the Germans really use English locks on the Enigma machine? I'm surprised, as they had plenty of their own great locks and German nationalism was running high in those times. The presenter sounds an awful lot like Oli D.
Good stuff.
