Luxor Stubby with Rectangular Lens

Thanks to Gunnar for the "heads-up" on this one. Several of these have appeared suddenly on eBay-France and eBay-Germany. Smooth stubby shell with slight flare at the bezel opening, and an entirely new-to-me lens with rectangular marble-style reflector in the center. I wonder how much light made it our the back... certainly would like to try one to see.
