Love your machines especially the pink one :-)
I have a 1955 Pfaff 230 that was given to me from a very dear Lady who use to make wedding dresses and lots of pearls appliques etc Very fine and beautiful work.
She gave it to me after her sons bought her a new machine. She told me that she was missing her old machine as the new one didn't feel as solid (plastic) LOL I found an antique desk that goes great with it and all tuned it up and it is working like new. I love it.
I have many sophisticated feet that I still have to discover how to use or what are they used for but it is my little treasure :-)
