Pistol Flashmeter

The Pistol Flashmeter dates from the very early 1900s and it is a metal cased dispenser for magnesium strips which when lit produce a brilliant white light for a short moment (depending on how much strip you have protruding), this one has some magnesium strip inside and a spare one also in the box, I lit some of this and it still works well even after 100+ years
