| + | 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. | ||
| + | |||
| + | Its 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 prime condition. | ||

| + | This machine was manufactured in about 1965 ([[http://www.boselli.com.br/museu/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. | ||
