I fear I may have opened my yap without fully engaging what there is left of my brain. It happens. I was talking about press photographers and the Beatles in the U. S. I suspect the Braun flash units were more popular in Britain than here. I looked up a photo of the Fab Four taking off for their tour coming over here and there were what looked like a few Braun units, others I could not identify and one Speed Graphic with flashbulbs. I seem to recall celeb photogs from Great Britain who would come to Hollywood for things like the Beatles and the Academy Awards would favor Braun units.
