This was my grandfathers calculator, which he used for some business calculations (he was a "master ('Meister') craftsman" painter in East Germany, responsible for a team) into the 1990s even after he already had an electronic calculator.
Does anybody have any information about this machine? I used to be able to do simple calculations with it, but nowadays I don't remember anything at all. I guess using trial and error I might be able to do additions and multiplications, but I would not be able to use even a fraction of that machine's capabilities. Sadly, there's no (surviving?) handbook.
There are plenty of resources for the Curta just a Google search away. Especially scans of the original manuals can be found. Try this one here: http://www.curta.de/kr34/
