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 and createed the list below of just Featherweight data.
The list starts with the USA made 221, then the UK made 221K, and finally the UK made 222K.
For modern seamstresses, it's too basic, sewing only a straight stitch without even a reverse setting on early models.
Even during the years of its manufacture it was sometimes ignored by the sewing public, as looking too much like a toy, and being too expensive for depression-era and wartime pocketbooks.

The following chart is provided to help you have a better idea of when your Singer Featherweight was manufactured.
The date often given by the Singer corporation as a machine's "birthdate" is actually the date the batches of serial numbers were released for production.
It's probably the above system that the 0800 number uses to so-accurately date machines and why they are sometimes multiples of ten years wrong as the 1 in the second example could be 1951, 61, 71, 81 or 91. ---------------------------- Date: Wed, -0500 From: [email protected]: Singer serial numbers Graham: After looking at the serial numbers of over 300 Featherweights that are on the database, I can guarantee you that there are no encrypted build dates in the serial numbers.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.Two Digit Dating System for Black Singer Featherweights Copyright @2007-2009 class221 Example: 221__AD 884639 Ignore the last 4 digits; then lookup 221__ AD 88……3/18/1935. Another distinguishing feature of the 221K4 is it is the only featherwieght model that has R. Sorry I don't have any definitave information about which colors each of the models were painted. The explanation tells us that: the S was the particular assembly line on which the machine was put together the 8 indicates 1981 the 247 indicates the day of the year (Sept 4) the 053 indicates that it was the 53rd machine built that day.Jim in Thomaston GA ---------------------------- Date: 26 Feb 96 EST From: Graham Forsdyke ([email protected]) Subject: CONTRIBUTIONS/To Lisa: Re factory designations. I have in front of me as I write a Singer explanation of serial numbers. The second example is A1061C027 the A indicates Anderson, South Carolina the 1 indicates 1981 the 061 indicates the day of the year (march 2) the C indicates the assembly line the 027 indicates the 27th machine that day.
Another check you can make to determine which model you have is to check the model number of the motor (see the plate mounted on the motor).
