They can be found but must be checked thoroughly to see if all the bobbin parts are complete as those are difficult to find from what I understand. Mine is complete. Dh would like her to go so I can oput some of my other finds in my sewing room and out of his garage space. I am undecided as of the moment. I do want a treadle but not sure what kind.
