Oh, how lovely! I learned to sew on my grandmother's 401 and it was the search for the same machine that started me collecting vintage machines. I bought the exact same cabinet and bench and I have filled all the drawers with vintage notions and accessories for it. Darning eggs, skirt markers, design disks - even a pair of Wiss pinking shears that came in the exact same box that my g-ma kept hers in, in between uses. :)
I love these beautiful machines and a seamstress is just about guaranteed to never outgrow it. It's just fabulous, isn't it?
You must be overjoyed - I'm so happy that you got the one that belonged to your mother! :)
