I also got one, and it still works. Mine has the paint a little worn out, on the top. Series starts with 33xxx. Thank you! for the video, otherwise i wouldn't know how to operate it
I saw a similar Walther Calculator made when I believe they were prevented from making fire arms. The body of the machine appeared to be cast in gunmetal and was quite intricately patterned. I did not dare try to work it as there was no way I wanted to break it. We used a Facit version on tanker ships before electronic calculators were more reasonably priced. Chief Officer when working out the cargo would have is office door shut but we could hear the whir whir ting whir of the machine going.
It's basically an Odhner, but with a carry mechanism in the counter register. PS, is it possible here to use both directions in division, like in some electric machines?
The carry mechanism in the counter register goes both ways, so sure, in division you can use turns in both directions to reduce the total number of turns of the crank. The bell will ring with every over/underflow, which can become rather annoying though.
