Chronology of cameras Huttig 

Thanks to Michel Tanghe, he is thanked, it is now quite problable that this detective camera is from the Huttig brand. Huttig used this name of Monopole with the same calligraphy. In the Mc Keown guide, the camera is not quite the same, especially in terms of the shape of the viewfinders windows , but the shape of the knobs is the same.
The only original feature of this Monopole detective is to have a distance setting using a displacement of the lens inside the unit in order to better protect it. On the left side of the camera (not shown), there is a tab to be slidable along a graduated scale that is moving the lens forward or backward.
