Seldom seen tri-fold instruction sheet (5.5x9.5" closed, 16.5x9.5" open) printed both sides for the set of Electrically Heated Clothing, Army Air Forces Type F-3A. Opens with an illustration of the full set of components, then a listing of items, steps in preparing for flight, how to operate, warning to navigators and instructions for mounting adapter plugs. Included is a paper label which was inserted in the package containing the "Trousers; Flying, Electric". This flight clothing set is very rare but if you happen to be lucky enough to have it in your collection, you really need this instruction sheet posted along side! Very good condition.
