She is a Minnesota New Model A sewing machine which was a badged machine sold by Sears and Roebuck. From what I can tell so far, it was made by the Domestic Sewing Machine Company for Sears after 1920. There is some good information here: http://www.kelsew.info/Domestic/domesticmodelsnolinks.html and here:http://www.enotes.com/topic/Singer_Model_27_and_127 and here: http://www.ismacs.net/sears/sears.html It is also possible that is is a clone of a Davis Model E. But from looking at the pictures, I think it was made by Domestic.
The serial # is 12524.
Here's the pics of the treadle head. It was froze up when I started. The cabinet is in equally awful condition. I actually took some water on a papertowel to clean up the worst of the grime, and she has had a liberal amount of sewing machine oil applied to her in order to get the works unfrozen, I have got the mechanism moving, and the bobbin winder will move up and down, but I can't get it to rotate and move. I am a little afraid to unscrew it, because some instructions for refurbing a similar Singer bobbin winder caution that unscrewing it will mean having to readjust it because there is a spring in there. I also can not get the plates on the base where the bobbins go in to slide at all, nor can I get the screw for the round plate next to them to move.
And now the photos of the cabinet:
And these are the attachments that came with it. One has "Greist" on it. I'd love to learn what they all do. Some I know, and others I think I might be able to figure out from similar Singer attachments.
And those are the pieces of the drawers that I have. I have everything except for one of the narrow top drawers. Just need to glue them back together and refinish them.
