Sturdy metal railway electric lamp with manually adjusted white or red colour lens. Probably dating from the mid 20th Century and bearing the branding for S.B.B. the Swiss Railways on the case front. I believe it is in working order but is sold untested. To use as is you will need a large torch battery like Everready 4R25. The knob on the front panel operates the lens selector and can be screwed down to maintain the selected colour. Inside is also a clip to hold a spare bulb. Well made railway handlamp with bracket handle.
