Folding Royer Teleroy
 Som Berthiot f/3.5 105mm lens
 Folding bi format: 4x5 and 6x9 cm with a "revolutionary" rangefinder as explained by René Royer in his 1950 presentation of the Téleroy device: "A new principle in the coupling of the rangefinder".
 Folding cameras are highly sought after by collectors, particularly for their aesthetic qualities, but also by enthusiasts of old processes, since with a 120 roll they allow for 6x9 photographs, and a simple contact is enough to reveal the image.
