British WW2 Lamp Electric No4

In a very good condition a British lamp electric No4, the lamp (almost a direct copy of the German ‘artas’ lamp) consists of a metal box, with a lens, reflector and bulb at the top centre of the front panel, two different coloured filters (red and green) are included that can be slid over this by using the two metal knobs on the front of the torch.  These were designed to allow the torch to be used at night for map reading without affecting the user’s night vision.
