I recall fooling with a 60s era Dormeyer model.  Not only did it use a
vibrator supply, but also a rechargeable stainless-steel enclosed
battery.  A very compact unit in comparison to those units using the
510V primary battery.  Either was vastly more compact than the Graflex
stroboflash-2x225V batteries in a very heavy supply.
