WWII USAAF. C-1 survival vest. ESM/1 emergency signal mirror.
One of the many survival tools issued to US aircrew in WWII was an emergency signaling mirror. This ESM/1 version made by General Electric Co. could be used in an emergency to attract ships or aircraft by reflecting sunlight. The mirror has directions for use printed on one side and still has the original braided string lanyard attached. Measures approximately 12.5 x 10cm. Good condition as per the photos but missing the string which could easily be replaced hence the low price
These mirrors were included in several of the life-raft kits, the C-1 survival vest, and the types E-5, E-11 and E-12 emergency kits
