Sakura Seiki Petal (complete set) I B Spy camera

Sakura Seiki Petal camera.
This camera, which is regarded by the Guinness Book of Records as the world's smallest camera, weighs only 90 grams, has a diameter of 2.7 cm and a depth of 1.5 cm. It can take six circular photos on film cut to a diameter of 2.5 cm. The camera is equipped with a 12mm fixed-focus lens and an f/5.6 aperture, and has a small external viewfinder. The shutter offers an instant mode with a 1/50 second exposure and a Bulb setting, without film transport or a mechanism to prevent double exposure.

The displayed model is back-engraved with "MIOJ", which stands for "Made in Occupied Japan". In the period from the end of the war until 1951, the US required this marking on all exported Japanese products instead of the traditional "Made in Japan".

Shutter responds correctly; the lens and viewfinder are clear

The documentation, supplied in a wooden box, is unique in that it fits on one page, printed on rice paper.

The photographs form a cohesive whole with the description.
