The diameter is 14.6 cm. Something like an alphabetic symbol is written on the outside, and the number "35" is written on the inside.
Dzus fastener, which is considered to be made in a foreign country, is attached. According to the previous owner, prewar Japanese Navy aircraft used foreign small parts. Also noteworthy is the 8 mm gun mark. Due to this hit, the outer surface of the paint and a part of the inner zipper are missing. It seems to be a valuable material.
