I have decided to donate at 3 machines, 2 in cabinets and one in a bentwood box. I am thinking about a 4th but it is a 128 and the slide plates are stuck tight. It is also a blackside EXCEPT for the hand wheel has the paperclip looking decoration on it - everything else is the blacksdide. That serial # is AH 610764 which means is was allotted 4/29/1948 with a run of 15,000. I don't know how much cleaning it needs either once I get the plates to move. She also doesn't sit quite fully into the base - like one of her hinges is off a bit or she's off a bit. Any suggestions? These machines have to be ready by this Saturday for the auction. The 2 in cabinets will be relatively simple to clean, I believe, unless they've lived with a smoker in a previous life.
