OH, your pictures make me long for my 401A . . . it has been in the shop. The needle began hitting the throat plate. I'm hoping to get it back this week to take on a Retreat. I bought it at an auction for $15, and had it completely serviced, using it joyfully for quite a long time. Then, it started giving me "thread-throw-up" on the back of my work, and I rushed it to my service guy, Gary Sink, Sink Sew 'n' Vac in Lebanon. Bad news is that he has a five-star reputation, and he's getting so busy! Cross your fingers for me that "she" comes home this week!
