The User's Review: Extra 35mm 1.8 Spy Camera during WW II

Scanned image from 'World War II' by S. Callery

First of all, I should say that I am NOT a user of this camera, not even have a chance to see or touch the real camera. My 8-year old son, Drew, read a picture book 'World War II' by Sean Callery and showed the picture of this camera on Page 87.

In the book, this camera is called 'Sure shot' (sure, not any one of Canon's Sure shot). 'This tiny camera, about 9 cm across, was seized from a spy after the war. Light, small, and easy to conceal, it could take pictures of documents at close range.'

I have not found any extra info on this tiny, special, spy tool on Google yet. Please let me know if you know anything about it. Thanks.
