Chronology of cameras Cornu 

Jean-Marc Guillaume, told me several remarks concerning the "Weekend Bob II", which he acquired in the USA.

The features of this model II are apparently on the following points:

1) The front plate which is different and is marked "Weekend BOB II", speeds ranging from 1/25 to 1/200 + B, the reference to the table on the back and apertures that range from 3.5 to 22
2) The lens block is still removable, but is equipped with a 50-3.5 Planyl lens and a small latch which is under the lens and provides angular positioning of the block to clear the vision in the finder lens, for example. It is the use that I have found but this gadget is a bit mysterious.

Clarifications given by Mr. Arnaud Saudax: The lens could be transformed into a telephoto lens by inserting three extension tubes and positioning a diverging lens in front of the lens block.
