The light aluminium frame was only 9-3/4" wide, even with the fabric rest down it still was only 14-1/2"....!I'm sure its still the smallest adult sewing machine ever produced.The Singer 99k sewing machine is small in size measuring only 12-1/2" wide, this image shows an early version the 99K (99K21 - 26) made between 1924 to 1954. The stitch length was adjusted via a screw and the machine did not stitch backwards.
The Singer 222K as shown has the sleeve arm or sometimes called tubular bed.
The Singer 221K was the same machine without the tubular bed, it also had the lift up fabric table like the 222K Both the 222K and 221K were tiny machines known as the original Singer Featherweight machines.
Unfortunately not many parts are available for machines of this age.
This one is a vintage Singer 12K sewing machine and was manufactured at the Singer plant in Glasgow, Scotland.
Its manufacturing year was 1955 to 1964 The Singer 66K is the large version of the Singer 99K.
Here the image shows a lovely 66K about 1920, originally may have been hand, electric or treadle operated.
The 127K had its bobbin winder in a high position and had the same type of vibrating shuttle or sometimes called boat shuttle or even bullet shuttle...!
It had a larger bed size at 14-1/2" The Singer 128K was manufactured around the same time as the 127K - 1912.
