...
It is a 101. The square needle plate, potted motor and stitch length disc on bed are the identifying features. They don't have a picture of the serial number. Even if there was, they are sometimes hard to read. If you look at the AD numbers, you will note that there are 6 number digits. If the first three digits are correct, that would put it in the 10000 that were allocated June 3, 1930.
