I would love to get a Bernina treadle! I've heard the old 400 series and lower can be treadled, even though you may have to remove the motor. They were sold to be either motorized or treadled. The key is to make sure the motor isn't internal to the machine but sitting outside. I keep my eyes open on Ebay and Craigslist, and I just know one of these days someone will put one up for sale at a price I can afford. I've got Singer and White treadles, but I love, love, love my Bernina electric machines (a 1031 and a 440), and I really would love to have a zigzag treadle. I figure an older Bernina would be perfect for that.
Oh well, I'll keep dreaming. I doubt the treadles coachmatthewsvhs saw were Berninas! If they were, I want to be where he or she is!! I've definitely seen treadles go for a song, but they were always Singers or New Homes or Franklins or Frees or ...
