My MIL had a 15-91 and I hadn't been bitten by the VSMAD (vintage sewing machine acquisition disorder) bug at the time she passed away, and it went to Viet Nam Vets. However, their family friend had a 15-91 and I got that one. Love it. My MIL also had loads of thread- all cotton thread on wooden spools. Some of it is over 50 years old, I am sure. If you pull on it, it breaks. Old all-cotton thread probably is not going to work in your machine. It's a shame, but there it is....
