The Brunsviga 10 is a mechanical calculator. It is an unusual machine for Brunsviga because it uses a stepped drum mechanism instead of pinwheels. About 10,000 were made made between 1932 and 1943. In 1948 they were made again, but then with a green case. In 1952 it was replaced with a redesigned new model, the Nova 10.
There is another video where I show the mechanism:
