Laurence (Amateursewing): I just purchased a Pfaff 34-4 and have been looking for information on the machine, including a user's manual, and came across your post from several years ago. While my machine is (much) different from the photos of yours, I thought you might know where I can find a manual and other basic information on the machine. For example, my version of the 34-4 has a roller foot and I would like to be able to install a more standard straight stitch foot, and have no idea if that is possible and, if so, what foot would fit.
I also noticed that at the time you posted a query, (8 years ago), you were living in Amsterdam. I live elsewhere in the Netherlands and come frequently to Amsterdam, and thought it might be possible sometime to meet us and share experiences with the Pfaff 34. Thanks, Nick
