U.S. Army Air Forces WWII M3 Flak Helmet

U.S. Army Air Forces WWII issue M3 Flak Helmet! World War Two American bomber crews in the skies over Europe needed something more than their leather flying helmets to provide them with shrapnel injuries, however it took a surprisingly long time for a new helmet to be developed and deployed to meet that need. Not until December of 1943 did the M3 reach the ETO, it was the first of three versions of the American flak helmet.
