Chronology of cameras Sem 

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

During the wartime and in the occupied zone, the Reyna camera arrived very discreetly. It did not appear in any catalogs or advertisements. It lacked leather covering due to restrictions, but on the early models, some parts were made of chromed brass, quickly replaced by aluminum.

Paul Royet would go on to design the Reyna Cross II based on the Reyna, optimizing the mechanism to simplify production. Soon, Cornu adopted several modifications, transitioning from the Reyna to the Reyna II.
- Reyna: Engraved "Reyna" on the front, later engraved "Reyna" on the top cover.
- Reyna II: Engraved "Reyna II Paris" on the top cover.
- Reyna Cross II: Engraved "Reyna Cross II" on the top cover.

Les tout premiers Reyna Cross comportent certaines pièces fournies par Cornu, comme le guide-film et le cache en laiton chromé. Les mécanismes de déclenchement et d'avance du film sont optimisés et simplifiés par rapport au Cornu. Les corps sont fournis par Aluvac, les objectifs par Berthiot, les obturateurs par Gitzo.
Le déclencheur par levier articulé de ce modèle est conforme au mode d'emploi du Reyna Cross II, dont les illustrations montrent que c'est à partir d'un Reyna I que Royet fit ses modifications.

L'obturateur Gitzo est marqué Reyna Paris par gravure chimique. Les lettres sont en relief. 
L'objectif Som Berthiot Paris Flor 3,5/50 mm est numéroté 266734.
