Inhaler Mask Bronzavia 1939 |
Bronzavia was a company specialized in the manufacturing of aviation equipment, including individual pilot gear providing oxygen and heating (1939), carburetors (for the Potez 63-11 aircraft), gas generators (1943), and more.
At least one patent filed by Bronzavia is found in the field of photography. This is Patent No. 820,091, published in 1937, concerning improvements made to focal-plane shutter cameras, particularly those used for aerial photography. The diagrams show a resemblance to the Type 70 cine-machine gun.
En 1938, the newspaper "L'Instantané" mentions "The Bronzavia camera, lightweight, handheld, with 3 lenses instantly interchangeable with focal lengths of 65, 100, and 160 mm, respectively." This may indeed refer to the Type 10.
The Nazi occupation is a dark period for the company, as its management committed to collaboration. Part of the equipment is relocated to Germany.

As the liberation approached, the company became a target of the Resistance.
The F.F.I. Operation in One Week (Rafales Journal, July 1944) The information below was gathered from enemy sources. This makes it even more valuable. At the Bronzavia Factories Around 7:30 PM, a group of about fifty "terrorists" forcibly entered the said factories through the gates on Chemin des Alouettes and Chemin de Grange-Rouge, just as the maintenance and supervisory staff were preparing to leave. These "terrorists," armed with submachine guns, initially incapacitated the five guards of the factory, as well as three requisitioned individuals assigned to guard a transformer. They then gathered in the factory hall around twenty employees, along with the guards and requisitioned individuals, whom they bound and held at gunpoint. Meanwhile, a number of "terrorists" compelled an employee to accompany them to the workshops, where they placed the explosive devices they had with them. They planted one device at each engine, and by 10:40 PM, 67 explosions had already occurred, with the first occurring around 9:30 PM. |
At the Liberation, the company and its leaders faced sanctions.

In 1946, Bronzavia had six factories and employed 4,000 people. There were six specialized departments, each with its own design office: radio department, engine power supply department, optics department (including photography), aeronautical boiler making department, general mechanical equipment on-board department, and electrical department. The CDH 44 cine-machine gun was mentioned among the flagship products, considered as a world-class product at the time.
The building in Courbevoie in 1937 |
The Courbevoie plant, established in 1932, closed between 1989 and 1994. The name disappeared during the same period, following the merger with Air Equipement, and after the name change to Lucas Aerospace Flight Control System.. __________
This is a description of a Type 10 perforated 70 mm aerial reconnaissance camera (No. 20) producing 6 x 7cm negatives. The large retractable sports viewfinder is tri-focal. Indeed, this monstrous camera features a turret with interchangeable lenses. One mount accommodated a 160mm focal length, while the other could hold either a 100mm or 250mm lens. The rotary shutter has a variable sector adjustable by a large unmarked button. The cocking mechanism is linked to the film advancement, achieved by pulling the right handle laterally, and the triggering is done by operating the trigger in front of the handle.
Lens "Bronzavia Courbevoie Anastigmat F/3.2 F:160 Type B No. 11". Aperture from 3.2 to 9. The standing lens is a "Bronzavia Courbevoie Anastigmat F/4.5 F:250 Type C No. 29" with focusing capabilities and a C-mount, which appears to be a recycling of the original 250.
