WW1 British Private Purchase Periscope, The Lifegu
With all private purchase items you just dont know whats going to turn up next. This periscope is called the Lifeguard and has survived in very nice condition with nearly all its black finish to both end caps and both mirrors without damage, concertina body works smoothly. The carry case again in very nice condition.
Of interest is that the material and clouser snaps on the carry case match the private purchase water bottle ive listed, item number 55049!
