This little mechanical calculator is one of my favorite objects. It came to me with what turned out to be a fouled 10s pin retaining ring; it was a bear to take apart, ‘machine’ a new part, and reassemble. But it works! And I love it!

Not to brag but I’ve successfully taken apart my Curta Model II, hand made a new tens bell retaining ring, reassembled the whole thing. Now one of the most beautiful computers ever made lives again! #curta #RetroComputing
