Mechanical calculators: FACIT C1-13 (third machine) * Back to Offline Hours * Back to Mechanical Calculators My brother-in-law found this machine stored in a friend's offices and gave me for my birthday in 2018. The machine's keyboard and the rotor advancement mechanism were locked, but the crank worked in its base position, and the counter and accumulator reset levers worked nicely. After opening it up, I found the locks that were frozen in place, cleaned and lubricated them, and the machine…

Mechanical calculators: FACIT C1-13 (second machine) * Back to Offline Hours * Back to Mechanical Calculators I purchased this machine at an online auction site in February 2011. It was in relatively bad condition, with rubber fixtures deteriorated, damaged painting, and corrosion on the bottom and front (behind the keyboard) plates. The main crank handle was firmly stuck, possibly due to some chemical used by the previous owner in an attempt to unlock it. I had to perform some “surgery” to g…

Mechanical calculators: FACIT C1-13 * Back to Offline Hours * Back to Mechanical Calculators I purchased this machine at an online auction site in February 2011. It was in quite good condition, apart from the natural deterioration of some rubber fixtures. Except for re-chrome plating the external levers, I kept its original look, including part of a sticker in the back from a maintenance shop in Belo Horizonte, Minas Gerais, Brazil.

Mechanical calculators: FACIT CA1-13 * Back to Offline Hours * Back to Mechanical Calculators This machine was manufactured by FACIT in Brazil, although I'm not certain when (the XNumber guide does not cover this machine's serial number). I bought it at an online auction site, in April 2024. No keys were missing, and the seller posted a video of the motor running. I received the machine by mail along with a box of parts the seller had taken out and didn't manage to put b…

Brunsviga, however, continued improving the design: according…
