Israeli military surplus.
My light came in very good condition for an item between 60 & 70 years old. It was intact w/no corrosion. The light even had the rare collimator covering the lens. And the bulb works! (3/4" pvc cut to fit battery compartnent + 2 cr123a batteries + jumper wire to complete circuit = working light!).
Looks great on my Uzi.
My flashlight came and it was pretty ugly, all spray painted and looked like it fell off a truck.
