Whether it was given a designating letter I do not know. There were four different models of the featherweight the 221-1, 221K4, 221K5,and 221K7. That is the only model of FW that Singer made with the switch on the light housing, all the others have the switch on the bed of the machine.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).Have just found burried deep in my archive the definitite answer to thos white/mint-green FWs. ---------------------------- Date: 07 Mar 96 EST From: Graham Forsdyke ([email protected]) Subject: Contribution re DOB of 221K " I have a pale turquoise FW (to me, it will always be mint green) with a SN of F (then a verrry faint "A") 131629. According to the records I'm using which were rescued from Kilbowie when the factory closed, the Singer Co went from EZ to FB without using FA at all.
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.

In 1905 some Singer's were manufactured under the name of Date: 23 Feb 96 EST From: Graham Forsdyke ([email protected]) Subject: Contributions/Factory designations There's been some confusion over Singer factory designation codes, some, understandably, believing that E was for England. I am using the word factory to describe a location where machines were either built or assembled.
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.
The factory designation, if it was not made in the USA, followed the model number. There are other examples for the plants in Scotland and in Germany.
As far as I can tell the SNs on British machines did not allow a to-the-day DOB until the 500 series started in 1973.
From what I read on Fanatics the Singer Co in the USA is dating many machines to the day (allbeit with a few errors).They do frequently, however, insist that certain machines are different model numbers than what they obviously are.The data we get from Singer in New Jersey is more frequently incorrect for the British machines than with the American.And there are many serial numbers, mostly the more recent FW's, that Singer is unable to give any estimate of build date on. Obviously in '55 the Black 221K was discontinued and the plant used for 222Ks with only Pale T 221Ks surviving the model change.---------------------------- Date: 06 Mar 96 EST From: Graham Forsdyke ([email protected]) Subject: Contribution/To all I"m just a little bit excited about this. From other information in the book I should be able to pin down the date of all K machines if Singer USA do not have the UK information. " Just how faint is that letter A in the SN, Nancy?I have written to them from ISMACS requesting this dating information and, if it comes (they're a funny lot at Singer nowadays) it will be interesting to see if there is any info on the K models. and from '74 the new SN system was introduced which was , in effect, a product coding rather than just a number.
