Japan No. 1
Japanese Air Force Morse Key No. 1

Japanese Key No. 1, was a morse key, manufactured before and during World War II (WWII) by Tokyo Radio Electric Co. Ltd. in Tokyo (Japan) — and probably by others as well — mainly for use in bombers, reconsaissance and transport airplanes, often with a Model 99 Tobi Mk.3 radio set.

The key is housed in a dark brown bakelite box with a hinged lid. and is mounted on a wooden base. According to the identification plate, fitted on the wooden base, the one shown here has serial number 21031, and was made in October 1943 by the Tokyo Radio Electric Co., Ltd.

When used inside an airplane, the key was usually bolted to the table, by fixating the three brass 'ears' at the left, right and rear edge of the wooden base panel [1][2].
