The Featherweight 221 Factory

I have tried to make it easier for you to find out the year your Featherweight was made by going through the serial number records published by Singer and pulling out all of the Featherweight data to put onto a list of just Featherweight data. You can check for yourself on the Singer website: NO LONGER SUPPORTED BY SINGER.

I have all the original information and you can download in .pdf format the production serial number lists by 2-letter prefix here:

AA          AB           AC          AD         AE          AF          AG

AH          AJ           AK          AL          AM         AN          AP

AR          AS-AT      EA          EB          EC          ED          EE

EF           EG          EH          EJ          EK          EL           EM

EN           EP          ER          ES          ET          EV          EW

EX

Here are the serial number lists for the Single Letter Prefix:

B     D     F     G     H     J      K     L     M     N     P     R     S     V     Y

Here is the rest of the Singer Serial Number information that I have:

No Letter Prefix Serial Numbers

 

Prefix Manufacture Locations

 

One Letter Prefix Machine Serial Numbers

There may be cases where your serial number does not fall within a Featherweight production range and may be listed under a different model number machine, such as a Model 15. This does not make the machine "rare" but is simply an error by Singer when they prepared the historical serial number lists or the data was simply recorded in error at the time of production.

I have tried to make the lists easier to use by having one each for the 221 and 221K, as well as a separate list for the 222K. Just click on the two letter prefix your machine has and scroll down until you find the appropriate range of serial numbers your machine falls within.
