The Primo is a view camera 35 mm produced by the Dutch company Nedinsco. It started as a license to build Steiner Steinette. This was an easy accomplishment because Nedinsco had bought the production tools Steiner and also had some tools for Nedinsco Argus, a license Gerlach Ideal Color 35 with many similar components to those of the Steinette, which could be explained by the that the same camera designer, Willy Uhrig, was involved. The first production was in 1958 with a batch of 100 cameras that were exactly like Steiner Steinette. All subsequent chambers (approx. 12 000) have a top cover and redesigned were made between 1958 and 1962. Primo that first production batch April 1958 can be easily identified by the fact that the accessory shoe is on the top and in the center of the chamber, while the later Primo have that shoe more integrated into the upper deck and slightly shifted to the left and back. The Venlo 3 element lens was designed and built by the Nedinsco itself at its factory in Venlo (NL). Nedinsco Optical is a company based in Venlo, Netherlands. It was founded in 1921 by Carl Zeiss.

In 1919 and 1920 they were transported (illegally) thousands of boxes full of equipment and storage for the Netherlands and Sweden.
