Hello. Today, I’d like to share a request we received from Mr. T.W. in Ohio, USA, to restore an original late-model Japanese Navy summer flight helmet.
こちらです
矢口工業株式会社の商標と記名布がついています。
It bears the Yaguchi Kogyo Co., Ltd. trademark and a name tag.
味方識別標識のミシン跡がありました。
There were sewing marks indicating that it once had a Hinomaru to distinguish friend from foe.
それでは修復箇所①～⑨を見ていきたいと思います。
Now, let’s take a look at restoration areas 1 through 9.
①右側 耳カバー欠損
②顎紐は実物では無いものが付けられている
① Right side: Missing ear flaps ② The chin strap attached is not the original one
③左側 耳カバー欠損
④バックルとその革は実物では無いものが付けられている
③ Left side: Missing ear flaps ④ The buckle and its leather strap are not the original
⑤後頭部 眼鏡ゴムバンド通しの革欠損
⑥ボタン欠損
⑤ Back of the head: Leather strap for passing the goggle strap is missing ⑥ Button missing
⑦庇ホック凸欠損、周囲の革も破損
⑧庇ホック凹欠損、周囲の革も破損
（表側に穴が空いています。通常ここに穴が空くことはありません）
⑦ Visor snap protrusion missing; surrounding leather also damaged ⑧ Visor snap recess missing; surrounding leather also damaged (There is a hole on the front side. Normally, there would not be a hole here.)
First, I tried placing this late-model flight helmet on a mannequin head, but because it has hardened and shrunk, it cannot be worn properly. Since these authentic flight helmets are so old (80 years), most of them have dried out and lost their original shape.
それでは修復後の後期型飛行帽をみていきましょう。
Now, let’s take a look at the late-model flight helmet after restoration.
①②同じ革質で製作
①② Made from the same leather
③④同じ革質で製作
③④ Made from the same leather
⑤同じ革質で製作
⑥当時物の猫目ボタンを使用し取り付け
そして、縫い跡があったところに味方識別の為の日の丸を直接縫い付けました。
⑤ Made from the same leather ⑥ Installed vintage cat-eye buttons And I sewed the Japanese flag directly onto the spot where the original stitching had been.
⑦穴を埋める為、革を二重に貼り合わせ、継ぎ目がわからないように処理しました。
⑧穴があいていましたので、同じ革質で庇を製作し交換いたしました。ホックもつけました。
⑦ To fill the hole, I laminated two layers of leather and finished the seam so it is invisible. ⑧ Since there was a hole, I made a new visor from the same type of leather and replaced it. I also attached a snap fastener.

On the back, the name, rank, and unit name are written in Japanese.
The model manufactured in 1936 features round ear cups; it is classified as Type 2 and does not have fur lining on the inside.
それでは、ヘッドマネキンにセットして見ていきましょう。
Now, let’s try fitting it onto the mannequin head.
こちらは初期頃の単座戦闘機などのパイロットの再現です。
耳カップの内側にフェルトカバーを当てて、耳穴から冷気が入らないように防寒対策をしています。
This recreates the look of a pilot in an early single-seat fighter aircraft. A felt liner is placed inside the ear cups to prevent cold air from entering through the ear holes, providing protection against the cold.
防寒覆面も装着
Also wearing a cold-weather mask.
こちらは、複座機の搭乗員の再現です。
伝声管（送話口・受話口）を装着し、機内との連絡通話に使用しました、必需品です。
This depicts a crew member in a two-seat aircraft. It is equipped with a Gospot (Voice Talker/ear tube), an essential item for in-cockpit communication.
次は一種航空頭巾でのセットも見てみましょう。
一種は内側が毛皮になっています。
Since we’re at it, let’s also take a look at a setup using a Type 1 flight helmet. The Type 1 is a flight helmet with a fur-lined interior.
Later, when aviation receivers were developed, the leather on the ear cups of these flight helmets was sometimes partially cut out to allow the receivers to be inserted and used.

Akitsu Maru: A Side Note It was a landing ship that was extremely advanced even by global standards, possessing the operational capability to deploy aircraft using a full-length flight deck designed to support landing forces.
