A First War Royal Flying Corps Cowl Helmet
In leather, with multiple broad arrow markings on interior, exhibiting mothing in addition to firm period wear, leather remains supple however has been stored flat for many years, as worn.
Provenance; This set of goggles were worn and used by Canadian Royal Flying Corps Pilot Gerald Alfred Learn, who was shot down on June 24th 1918 while engaged with three German trip planes.
Footnote: One of the earliest 'standard' types of helmet used by British aviators during the First World War, from 1916. This is a variant and does not feature the adjustable strap and buckle arrangement that could be selected to wear at the chin or moved to the back of the neck. Whilst cowl, or hood helmets, gave protection to the head and neck from the cold, movement of the head was restricted and was therefore a disadvantage for pilots and a reason why mainly observers tended to adopt them.
