It also works the other way too. Vintage feet and attachments will fit newer machines. My ancient old Singer buttonholer which is older than I am, fits my Janome 6500 just fine. I like having buttonholes that are exact and the buttonholer does a much better job than the built in one on my Janome. Generally short shank attachments will fit other low shank machines. The exceptions seem to be Bernina and Husqvarna although I did use a low shank even feed foot (walking foot) on a Bernina machine using the Bernina adaptor post.
