Original World War Two American HS-23 Headphone Set, with ANB-H-1 Receivers

An original item in good condition, being the leather covered HB-7 headband, leading to bakelite ANB-H-1 receivers and large yellow chamois covers. Black plug on the wiring denotes the receivers are the HS-23 version (earlier war) and not the late and post-war HS-33 (red plug).
