Rulex

The Rulex is a series of leaf shutter made by the Japanese company Neumann & Heilemann in the late 1930s and early 1940s. Three versions were offered, called Rulex A, B and D, the D being the cheapest one.

The name "Rulex" already appeared on the shutter plates of some German cameras in the 1920s, it is unknown if it was the shutter name or the model name, and it is unknown if there was a relationship with the Japanese Rulex shutter.
