The famous/infamous LKpN101 summer flight helmet was very popular with German fighter and bomber pilots throughout World War II. This net top or mesh lightweight flight helmet was designed without a chinstrap, which provided greater comfort for the wearer. It has leather receiver cups with receiver, and a leather and Bakelite throat microphone unit. The data label has the manufacturer's code "hdc" for Luftfahrtgerätewerk Hakenfelde GmbH, Berlin-Spandau. The throat mic is marked "Mi4b" and "Ln26779-2." The plug is marked "BLK v F1 27560." The extremely rare Model 10-69 oxygen mask has the size marking "Gr. IV" (the largest size made) and has a crocodile clip. Entering service in 1937, the Model 10-69 oxygen mask is considered by Luftwaffe flying gear collectors as a "Holy Grail." It is one of the rarest pieces of World War II Luftwaffe flight gear. Includes a set of period correct tinted goggles. Provenance: The Putnam Green/Sycamore Collection
