I scored a great set of HB-7 Headphones fitted with ANB-H-1 receivers and the red PL-354 bail out plug. (HS-33?) and it came with a black JK-26 extension plug. The receivers are Made by SHURE Brothers, Chicago, USA they are in great shape. the leather is still soft and plyable. they came with one original MC-162-A rubber ear pad that is also soft and plyable. too bad the other was missing but I got a post war Japan made replacement of the same MC-162-A spec that match perfectly to the original from Bells Aviation. the leather has a name written on top: ELLIOTT I am in contact with the seller who says his father received them as a gift from a friend who owned them in the war. he is selling off his father's personal belongings as he is very old and frail. I am hoping to find out if he recalls the gentleman and what plane or what theater of operation he flew. I also purchased a NOS T-30-S throat mic to go with it. ... more items to post soon!
