| I had the external levers re-chromed, and found a small firm that agreed to give its cover a new coat of electrostatic paint, which looks able to withstand at least another 100 years (the firm paints cases for public telephones). The acrylic display covers were also damaged, and I attempted some restoration in one of them, to be improved on later. I cleaned the mechanism and lubricated it, without fully disassembling the machine -- however, a full revision is due soon. | I had the external levers re-chromed, and found a small firm that agreed to give its cover a new coat of electrostatic paint, which looks able to withstand at least another 100 years (the firm paints cases for public telephones).

| - | This machine was manufactured in c1966 ([[http://museu.boselli.com.br/Facit%20C1%20F.htm|ref]]), at FACIT's unit in Juiz de Fora, Minas Gerais, Brazil. Later machines had a plastic cover, but this one is in die-cast metal. It is not identical to my other C1-13, though: arrow keys are a different color, and the logo in the back is in a single plastic strip, whereas the previous one has each letter attached individually to the back. The serial number indicates that this one has been manufactured more recently. | + | This machine was manufactured in c1966 ([[http://www.boselli.com.br/museu/Facit%20C1%20F.htm|ref]]), at FACIT's unit in Juiz de Fora, Minas Gerais, Brazil.
