By Windak. Waistcoat, Electrically Heated, Type F, 24 Volt. Stores reference 22c/957. Brown cotton 'kimono' jacket with integral wiring/heating element and press stud connectors at the wrist and waist to accomodate type D glove liners and 'extension' cords that linked to electrically heated socks/bootees. Unfortunately the 'umbilical' connector cord and 3-pin plug have been removed. The waistcoat is a bit soiled and the cotton is creased/crumpled as is normal with these garments. There are a few small holes at the neck near the label and on the front (as shown) plus minor verdigris deposits on some of the connectors. Air Ministry labelled. Now highly sought after. Stock code J27164.
