This is a set of original Korean War OD#7 HBT helmet liner accessories. Both pieces were recovered from the same helmet liner and are marked with the laundry number 'S-3071'. The headband features 1952-53 markings and early-war green painted steel clips. The headband's leather shows signs of use, but is still in good condition. The neckband's markings have faded, however it is most likely dated the same as the headband.
