I bought a Pfaff 1471 in the early 80's. I needed the threader hook replaced a few years ago and heard my repair guy say, "yep, I can still get that part". Gave me a chill, so I bought a Pfaff Quilt expression at clearance prices. Sure enough, the motherboard went on my 1471 a few months later and it looks like it can't be repaired. I bought a featherweight, and began restoration of my mom's treadle.
