| This machine was manufactured by FACIT in Sweden, in 1948 (see [[http://www.xnumber.com/xnumber/facit_TK.htm|here]]). It was the first calculator I bought in an online auction site, in November 2010. It was in pretty bad shape, including a bright green painting and missing screws in the cover. Worse than that, the previous owner's attempts at painting the exterior have resulted in mostly erased number wheels. Unfortunately, I couldn't see that in the site's photos. | This machine was manufactured by FACIT in Sweden, in 1948 (see [[http://www.xnumber.com/xnumber/facit_TK.htm|here]]).

| - | I partially disassembled the machine, cleaning everything I dared removing, using John Wolff's instructions for the Facit C1-13, a much later model. I was able to fully disassemble the registers, and in the process I printed new numbers for the wheels. I designed and printed a thin strip of paper in a laser printer, cut each strip to size and glued each of them to a wheel. I also restored the plastic windows with acetate, and had the main levers and indicators re-chrome plated. Finally, the casing was repainted with the appropriate color, the Facit label was restored, and new screws were used externally -- all coming from savings and scraps of old desktop PC cases. | + | I partially disassembled the machine, cleaning everything I dared removing, using John Wolff's instructions for the Facit C1-13 (see below), a later model with several improvements.

| I have no pictures of the partially disassembled machine, since this was my first one and I was unsure as to being able to put it back together, let alone in working condition. But here go some pictures of the final result. | I have no pictures of the partially disassembled machine, since this was my first one and I was unsure as to being able to put it back together, let alone in working condition.
