Dating your vintage Singer sewing machine

Some people make the same mistakes when dating an old vintage Singer sewing machine.
EVERY Singer has a serial number (except the Singer toys). It is a long number, stamped on the frame of the machine.
Often the age (and the factory among others) can be determined using websites or the app.

The serial number is NOT the number on the removable motor.
The serial number is NOT stamped on any random part
The serial number is NOT the short MODEL number. (No, a 191b (191B) is NOT made in 1918)
The production year is NOT stamped on the machine, anywhere.
The production year is NOT the date the original patent was licensed.

(NOTE: Unfortunately not all records have survived, so not all machines can be dated accurately.)
