shorthand in the movies

My wife and I were watching Alfred Hitchcock's Sabotage last night, and there was a scene with a newspaper reporter writing shorthand notes for a story. I could read it--it was clearly Gregg.

Only problem was, the story takes place in London, in the 1930s.

Anyone know whether this might have been possible? I would have thought it would certainly have been Pitman.
