IJNAF 1930 TYPE, EARLY PATTERN
The early pattern of the 1930 Type summer helmet of the Imperial Japanese Naval Air Force was basically identical to a model already in use since the 1920s. It is constructed from six triangular leather segments and features a short, turn down bill which would be fixed in the up position by means of a stud fastener.
Two ear flaps covering the ear openings are buttoned down near the cheek while a leather chin strap is fixed on the right and buckles to the left.
A thin leather crown strap around the head is to be tightened by a small buckle at the rear, where two additional button down goggle straps complete the helmet which is lined with green cotton twill.
A typical IJNAF cloth patch which would feature information to ID the pilot is stitched to the rear near the nape while on the inside of the helmet we find a manufacturer's label.
