Hi, it's Lamp, Electric, No.1 and JL is Joseph Lucas (prince of insufficient light) Limited.

 

It is/was the standard military lantern during WW2 the shutter is to direct all the light downwards so that you can see where you're treading without showing light that would give your position away to aircraft or other troops. The knob on the front of the lens rotates a red filter for use at night so that it won't affect your night vision.

 

The battery is the long-obsolete 800 size, used in cycle lamps until they switched to paired U2 or 'D' cell size. (1970s?)

 

(It consisted of two zinc carbon cells (same size as used in the 996 lantern battery that is still available) in a cardboard case with a "figure of 8" profile viewed from the top. A brass spring strip on the top was the +ve contact and a second strip on the front was the -ve connection. The cells were connected in series to give 3 volts.)
