I have an assortment. Two featherweights, Viking mega quilter, Spartan, Singer 99, Pfaff 2340, Pfaff 102 (treadle),Kenmore (1945 model) and I just bought a 630 Brother to lean to embroidery. All except te Pfaff102 gets regular use. I have them all set up with different tread in them and use them as I need that color thread. None are named. At my stage of the game, I am lucky to remember the brands.
