| - | 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. Apart from 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. It's mechanism, however, was hardened by the deterioration of oils and greases used in its lubrication from back in the 1960s and possibly the 1970s. I did a complete disassembly, cleaning and reassembly, along with a (modern) lubrication, and the machine is back in its prime condition. | + | * [[calc|Back to Mechanical Calculators]] |
| - | This machine was manufactured in about 1965 ([[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. | + | I purchased this machine at an online auction site in February 2011.
