Authorized reproduction of the Singer catalog dated 1913. It shows commonly found models and cabinets of that period. The models of machines include the 127-3, 15-30, 115-1, 66-1, 24-50, 28-4, 24-51, 29-4 and 31-15. There are illustrations of these models, that is the machine heads and the cabinets that were available for them. It is a very nice advertising piece. It is full of great information and priceless illustrations. I am sure that you will find it useful in researching your collection of sewing machines.
