Chronology of cameras Cornu
Around 1940, Cornu requested Aluvac to cast the bodies and backs of a small 24 x 36 camera in aluminum. These parts were marked as Aluvac 3439 and Aluvac 3440. These components were used for about two decades by two companies to produce numerous popular camera models.
The Société des Établissements Modernes de Mécanique Générale et de Décolletage Jean Cros was established in Saint-Étienne just before 1939 with state funding to support the war effort. Jean Cros had Aluvac mold rocket fins for him.
After the defeat, Jean Cros, forced to refocus his activities in the civilian sector, considered entering the camera manufacturing business. He reconnected with Paul Royet, who had been a "special assignment" employee in his factory until his demobilization, to offer him the position of Director of the photographic section, where everything had to be created from scratch.
In 1941, Jean Cros, the director of SEMM, obtained a license from Cornu to manufacture a camera in Saint-Étienne using these parts. Paul Royet, the future director of SEM, successfully carried out this project
The Ontobloc cameras succeeded the Reyna cameras by abandoning the telescopic lens mount in favor of a rigid mount, simplifying construction and avoiding some issues during shooting. This is what the name "Ontobloc" signifies.
Ontobloc, which is almost a rigid Reyna II.
Ontobloc II, where the integrated viewfinder from the foundry is replaced by a chromed cover, with a richer and less austere appearance.
Ontobloc III, featuring a dual helicoid focus and a lens that opens to at least f/2.8.
In each of these models, you'll find numerous variations due to artisanal construction and the supply challenges of the post-war period.
The first Ontobloc I model retains the needle-type closure mechanism from the Reyna and Reyna-Cross II cameras.
The second model, built on the Sem-Kim body, features a hinged closure and an external latch.

This Ontobloc presents the not very common characteristic to be equipped with a Kodak lens and a Compur shutter, both originating in Germany.
In very a good state of custody, this camera was obviously not used much.
Like all the cameras of this model, it bears a number. This one classifies rather our specimen in first part of the production.
This optical group according to any probability be assembled of origin. The shortage of shutters, just after war, explains why for one short duration the production of the German factories was requisitioned to provide certain French manufacturers.
