Well, that is what it must be Mike. The camera had a 2 pin plug on the lens/shutter and the other end of the household plug was a female version to fit the camera. There were also acessories for this that used similar cables. I have a box of flash units, lenses and cords for this type of unit. I have had to get an adaptor so that I can put a modern flash onto some of my old camera/lens combinations. They make them.
