WW2 USAAF Flight Pants, Heated Suit Type F, Vintage

These are flight pants from the U.S. Army Air Forces (USAAF) during World War II.
This is a genuine item with U.S.A.A.F. marking and a contract number on the inner tag.

Based on its shape, it is likely an electrically heated flight suit (Type F series) for high-altitude flight at the time.
It is a bib-type with suspenders, a long zipper on the front, and side lacing, featuring a special structure different from regular flight pants.
Originally, this equipment was powered by the aircraft, but the power cord (hose) is missing.

Seven TALON zippers are used.
