PALMGRENS TYP 4
Palmgrens type 4 cloth flying helmet, summer.
The fourth standardized Flygvapnet flying helmet from Palmgrens saw widespread use into the postwar era. The overall pattern reminds us of the construction of British RAF/FAA C-type helmets and consists of seven segments of yellow cloth, the four center segments provided with eyelets for aeration.
Size adjustments are made by means of a leather strap at the rear inside the cloth shell. Inside the otherwise unlined helmet we find black ink stamps depicting the Tre Kronor and size 56, while the brim and neck are reinforced with dark green felt patches. A snug fit can be achieved by means of a leather strap, sewn onto the left cheek and a two-ring buckle with leather fitting attached to the right cheek.
Inside the ear openings, chamois padded donuts add to the wearer’s comfort and noise insulation, while on the outside two leather ear cups are sewn onto the helmet. The latter are equipped with vertical zippers marked GUSUM. While British helmets used rubber foam inserts, the Swedes used chamois-lined ear pad inserts for improved noise insulation.
The inner leather structure of the ear cups is forming a ring shaped pocket for earphones, with the wiring exiting at the bottom. On the outside, the ear cups were retrofitted with two metal studs to attach an O2 mask with a hook arrangement. No other provisions to attach late style oxygen masks are present.
Further features contain a single rear goggle strap retaining loop, secured by a push button, a system of five leather enforced press studs to attach a leather skull cap, and a series of simplified retaining straps, loops and buttons to attach and guide communication equipment wiring.
The skull cap is made of five segments of yellow leather and lined with chamois. It is marked with an ink stamp indicating a size, and can be attached to the type 4 helmet by means of five press buttons, providing additional insulation and protection.
