I cannot offer you any information about you machine. My mother had one in the l940's and I learned to sew on it when I was five years old (1942). It had a beautiful cabinet. The treadle mechanism was inside the cabinet. A door opened 180 degrees and formed the support for the top of cabinet which also opened 180 degrees. This was the work surface. The head of the machine lifted up and was secured by the lip of the cabinet. I remember it as being beautiful and have wished many times that I still had it. My mom was anxious for an electric machine and did get a Singer 201. I had that machine for many years until someone stole it. Good luck to you in your search. I will be anxious to see a picture of it.
