Coronet is a British camera manufacturer based in Birmingham. The company was founded in 1926 by F. W. Pettifer. She built cheap box and bellows cameras until 1967. After the war, she collaborated with the French company Tiranty to avoid import restrictions. That is why some models of Coronet cameras were also produced in France, with Boyer optics. Coronet also produced films under its own brands, including Corochrome. The camera of the collection has a primitive lens extension mechanism, one shutter speed. It is a model produced since 1926. The Coronet for the 620 type film was bought with an efficient shutter with a jammed lens shift. It was made in France. Acquisition cost PLN 79.
