Flashlight 3 Rotary Color Lenses

Vintage period flashlight which I believe might be not be German. It might be French or Italian or Czech... I didn't see any markings. The 3 colored lenses of this one are on a rotating disc in the black out cover. It has some overpainted areas where it probably rusted and was cleaned up. It is in working order although the contacts could use some cleaning.Batteriesandspare lightbulbsavailable separately.
