Mitch's Mom, I guess I'd never thought about vintage and sergers in the same sentence. Thanks for the tip about checking out parts. These are Babylocks which are generally thought to be the best, but who knows about these particular models. They were in a carriage house and look like no one has touched them in many years. They aren't very large, but my, they are heavy, probably 20 lbs each in a small package.
Don't know yet if they work, first I've got to clean them up. Any suggestions for cleaning them--it's just surface dirt. I can't use much in the way of chemicals, and I don't think they need anything strong.
I do have an OSMG who services my machines who is also a Babylock dealer. I'll probably ask him if they are salvageable--if not, I'll give them to him for parts.
I thought I'd do some research on them ahead of time so I knew whether or not to even take them.
Thanks again for your idea, SUe
