Swiss modified late pattern Type C leather flying helmet
Having entered a career with the Swiss Air Force, this C-Type was subject to a bunch of modifications.
While the basic construction was not altered or "punched", ANB-H-1 earphones are fitted into American style sewn-on / stud-secured ear pockets. The internal wiring has been modified for both American and British communication equipment. It leads from the receivers into a combined braided/rubber cord arrangement ending into a six-pole plug. In our case an adapter eventually feeds the whole package into a British bell plug. If required, a different adapter would probably end into an American plug.
This arrangement calls for the use of a throat microphone, thus the late pattern C-Type's typical sewn-on mask microphone socket on the left became obsolete and was by consequence removed.
An American or British oxygen mask can be attached by means of a series of studs on the left and a hook on the right.
Additional side-mounted wire loops and an adjustable top center strap provide attachment points for a three-strap oxygen mask, like the Swiss Huggenberger mask shown on the picture on the lower right. The document originates from 1954 and shows the helmet for use with the Swiss C-3603.
After being retired as a combat aircraft by 1952, the sturdy K+W C-3603 was used as a target tug, illuminated target aircraft for anti-aircraft gunners and transport aircraft (dropping wooden cargo containers with emergency equipment) until the early 1970ies.
This picture shows a Bücker 131 pilot during a training mission in early 1970. He is wearing a modified Type C helmet with B-8 goggles and a Type A-14 oxygen mask. The latter is used as a microphone carrier (and face protection), as indicated by the missing oxygen hose. A Bückercombi and leather gloves complete the outfit.
