| I purchased this machine in August 2012 from an online auction site. It had obviously suffered from a hazardous storage environment, since oxidation in its cover caused extensive damage to the painting. Inside, I realized that liquid has probably been spilled over the keyboard, since there was a big stained area and superficial oxidation in the front section of its base plate. Some rubber fixtures were also degraded. A pair of rollers at the back, used to slide the 7.5kg machine on top of an office desk, was practically molten. I replaced the rollers with wood. I also repainted the machine, trying to follow the original colors as captured by images of other machines found online. A thorough disassembly, cleaning and reassembly was necessary to restore the machine to working status, since dried out oils and greases from the 1960s seriously hampered its mechanisms. Apart from the deteriorated rubber fixtures, no other parts were missing or damaged. | I purchased this machine in August 2012 from an online auction site.
