I have a Pfaff 130, Made In Germany, in 1950, according to the serial number. This particular model is a collector's item for Pfaff lovers. I bought brand new in 1968 a Pfaff 262, a much newer version, but most of the feet between the 130 and 262 are interchangeable. I would get a second opinion on the rust situation. Also, there is a guy, Zeus Machines, that totally restores Pfaffs, especially the 130 models. You might google and talk to him.
