Desirable U.S. Air Service pilot helmet, Western Electric No. 1A, complete with rare electrical cord for interfacing with the S.C.R. 57 interphone and the S.C.R. 59 radio receiver. Helmet leather is excellent and supple. While cord is excellent the helmet headphones are missing. I have one of these in my personal collection and I paid 50% more for it than I am asking here. Very unusual to find this helmet with electric cord.
