Dating a featherweight sewing machine
These two machines both have build dates of 8/11/52 (along with 10 other machines on the survey).
You can see that Singer obviously used a standard progression in assigning numbers.
Also, I haven't heard of Singer giving out what appear to be bad build dates on their machines.
They do frequently, however, insist that certain machines are different model numbers than what they obviously are.
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.

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.
Introduced as the model 221 during the 1933 World's Fair, the model boasted aluminum construction, small size, and a weight of only 11 pounds (5 kg).
