Hi Elliot, I have to confess, I don’t remember what flash I had. I made that shot – in fact both of them – with an Ikoflex, which was sort of the poor-man’s Rolleiflex in those days, but had a Zeiss lens that was at least the equivalent of the one on the Rollei. I know I used a flash gun: the kind that took relatively small flash bulbs. I think I had a bracket that held the flash on the camera, but I can’t be sure. Compared with what we work with nowadays, it was a pretty primitive rig.
