Any knowledge on the Graflex Stobonar IV head disassembling out there? I have four of these beige heads two good, one flaky and a dead unit. The electronics don’t scare me, but I need some help on where to start the disassembly. I would like to keep the cases intact.
The metal bezel on the front lens does appear to be free of the body, but I don't what to force the issue.

Is Strobonar the same as Stroboflash?
