Can you make out what the yellow stencil says in photo IMG_4344 ? "INFERNO SPECULAR"? Is "Kliegl Bros." embossed above that? A Kliegl hell machine, then, obvs.
But the first one... is there another shot of the backside of it? Looks kind of like a Carbon ArcStrobe. The other, as Derek has shown, is really just the original version of a Great American Scene Machine

Old post but a filament 2Kw fixture of unknown brand - two known of in exsisting, but were to replace carbon arc special effects fixtures. Thought on the age of them - somewhere in the 1950's.
