Wow! I've come a long way with sewing machines since this was posted. I really like sewing machines. I'm equally smitten with tools of all sorts, though. After significantly thinning the herd, I still have 10 sewing machines.
Fortunately, my Mom's husband gave me her 15-91, after I offered to buy it. It was allocated during the month/year of my birth. I really don't know what year my father gave it to her. It was a Christmas present.
