A Singer Treadle. Later, in 1948-1949 I learned in Home Ec class in Glenwood Park, WV, I think those were the black Singers, but were electric. I loved to sew from day one., made all my Dolls clothing, and my own also as I got better. Still love it. Just received my 9th Machine today. A Brother 140 Electra Zig Zag, Aqua colored.
