Authorized reproduction of a Singer sewing machine model recognition guide. You see by 1982, which is what this is dated, their salesmen simply could not recognize every Singer sewing machine that they came across and neither can we. Each model is illustrated, from the model 12, made in 1865 through the 7000 series, made in 1982. There is basic information about each model and its years of production are noted for most of them. There is lots of great information in it which I am sure you will find useful including some interesting details about serial numbers.
