Firstly I know nothing about military things...but I picked this up because I loved it , even though I wouldt consider myself a collector at all.
Having said all that Ive already posted about two other items
Ive read that this was produced before WW11 and was used by GI's on land.
I've also read that it was used with parachutists.
Ive also read much rarer than the other issue equiptment. It flashes for morse code and although batteries obviously are not original I believe everything else about it is.
The bulb has a bit of blue colour in it when off.
Any info greatly appreciated.
