Linda, what is the number on the '78 Kenmore? I'm thinking this one fits in that range because it's still metal inside. I don't need the machine, but I'd like to sew on it. I have a friend whose 1972 Elna SU bit the dust and she's still in mourning. She's not getting along with the new Janome she replaced it with. I feel bad for her, but not bad enough to give up my '73 twin which was the replacement for my '61 Kenmore. For $21, the Kenmore could be a usable machine. I forgot to look to see if it's short shank so the Elna attachments would fit.
