A 15-91 for sale here in San Diego is in a cabinet and has the matching stool they are asking $150.00. I absolutely love my 15-91. It is from 1949 or 1950 - still haven't checked it out. It belonged to my mother, it was a wedding present from her parents and my parents got married in May 1950. I was very tempted to buy the one for sale because I do not have the stool that came with my machine, but wasn't sure what I would do with the new machine. I have a hard time letting go of machines that I acquire. To me it is worth it and if I did not have mine, I would gladly pay the $150.00.
