Brunsviga-AS8-Prosp-1950

I bought at eBAY for a very good price a variant of this calculator, made in Germany from 1949 to 1951. As is practically normal for eBAY stuff, it did not work, but was in good visual condition. A first problem to solve was how to remove the case, as the axis with the paper advance knob blocked this!
