I have a ton of cabinets in my house - most of them only fit Kenmore or Free Westinghouse - some JC Penny machines won't fit Singer cases or tables and the Singers won't go in those cases or cabinets. I don't know about Elna, Bernina, Pfaff, Viking or Necchi fitting in a Singer cabinet. Some machines weren't made to go on the table hinges. Nancy is right the clones will fit in some of the Singer cabinets. Singers come in several sizes so you have to have the same base. Treadles are a whole different game.
