Hey brought this unseen today. Looks like a lamp but has exposure times on shade. Made by WATA in germany i think in the 1940s. Does anyone no more about this.Cant just be a safe light?
Looks like a strobe??? X and M Kontact is the flash sync setting, with X being electronic flash, and M being flashbulbs (which need more time to flash after being triggered, so M triggers very slightly sooner than X.) Looks like they expect you to set a slower shutter speed if your camera is on X sync to accommodate the timing difference.
Does the end of that cable have a connector that looks something like this? That's a PC connector that would connect to the camera's PC socket to trigger the flash. Modern cameras won't have that connector, but you can get a PC adapter that sits on the camera's hotshoe to trigger old lights like this.
Looks like a strobe to me as well.
From internet.......
