I, too, have my Mom's 401A ( which I bought for her in 1955) complete with 5 cams and a lot of feet. I paid more for the cherrywood cabinet than I did for the machine. LOL. I learned how to sew on that machine and made many Prom dresses for myself. It has been in storage since 1993 when Mom passed away. I had it cleaned and serviced 2 yrs. ago, but have yet to use it; yesterday I stupidly did a number on my Viking SE and jammed (or froze up) the motor and now am taking it into the dealer for repair tomorrow! So, I dragged the 401A out of the closet this a.m. to refresh
my memory and will give her a spin later today. Of course I have 4 different projects going and I have to work on at least one of them while the SE is in for repairs. Boy, is my stupidity going to cost me $$$.
