AI-assisted summary
Description from the seller
The Physiograph 4.5x6, also known as Physio-Pocket, is a very rare spy camera designed by engineers Edmund and Léon Bloch and produced around 1904. The two names essentially refer to the same model: Physiographe is a later designation.
Camouflaged as a regular monocle, this ingenious camera integrates a complete recording system, with a 90° angled viewfinder and a side-mounted lens, enabling photography in an extremely discreet manner. The body is made of metal clad in Moroccan leather, with high-quality finishes.
It features a back for metal plates sized 4.5×6 cm, achromatic lenses in Jena glass, and the prestigious Krauss Tessar f/6.3 lens, renowned for its excellent optical performance.
