World War 1 British RFC (Royal Flying Corps) Cowl Pattern Leather Flying Helmet. One of the earliest 'standard' types of helmet used by British aviators during the First World War. It's missing the leather tightening straps and buckles. The flying helmet is in heavily used and worn condition, the fur lining is partly damaged but overall it's still in good condition. The helmet is complete with manufacturer's label and dated 1918. Extremely rare original WW1 RFC Flying helmet!
