Last year I picked up a 1930 Singer Treadle machine for making light weight gear. Then last month my sister gave me the machine that my mother used, another Singer Treadle machine, with an instruction manual from 1929!
The 1930 machine has a shuttle style bobbin that gives me trouble. The 1929 machine has a more modern bobbin mechanism that works well; it may actually be a later model. It does an excellent job with extremely light fabric. I use it for hemming 1.1 nylon and making ultra light freezer bag cozies.
The pretty one on the left is the 1930 model.
