I have recently been watching these Pfaff machines on ebay I have only seen those marked, "1222" and "1222E", but have not been able to tell the difference. I think I read somewhere that the 1222 has more metal pieces. Can anyone explain the difference for sure!! Many of them are, "Untested, pedal missing, for parts only"....this tells me that they don't work but the seller does not want to admit it. Even these machines sell, so are they easy to fix? Parts available?
