Class 127 Survey Results
There are 4 machines included in the survey ranging from 1916-1926.
They are all treadles with shuttle bobbins, high mounted bobbin winders, and spoked chrome edged balance wheels.
They all have shiny black finishes. All have flat face plates and round plates on the back right side with floral/leaf designs.
The stitch length adjustment is made with an unmarked knob on the front right side (longer to right, shorter to left).
They have no reverse or zigzag stitch option.
The upper thread tension is unmarked in the front on the left side of the machine.
All 127s in the survey had Sphinx decals and large 1 5/8 inch Singer medallions.
The head measures 14.25 from face plate to far end of balance wheel and the bed measures 14.5 inches wide by 7 inches across.
The machines were straight needle and low shank.
The 127 is threaded from left to right.
Class 128 Survey Results
There are 6 machines in the survey ranging from 1919 - 1951, all electrics, 5 with foot pedal, 1 with knee lever.
All had shuttle bobbins and high mounted bobbin winders.
The earlier machines had spoked chrome edged balance wheels and the later machines (1948,1951) had solid, black balance wheels.
The early machines also had a shiny black finish while the 48 and 51 had the Godzilla (matte, crinkle) finish. (Editor's Note: The official Singer term for this finish is "wrinkled".)
They all had a flat face plate, the early ones with a grape design, the 48 and 51 were lined. The early ones had upside down pear shaped plate with grape design on the back right side, the 48 and 51 had round plates with lined design.
The stitch length adjustment is an unmarked knob on the front right side (lengthen to right, shorten to left). The 128 has no reverse or zigzag stitch option.
The upper thread tension is in the front on the left side and is not numbered.
The decals were assorted from 1919 heavy floral, 1919 red green and gold, 1937 minimal decals, 1937 simple geometric, scallop design, 1948 Singer only, 1951 center bed design only no border.
All machines had the large 1 5/8 inch Singer medallion (the 1951 has a centennial medallion).
The head measures 12.5 inch from face plate to far side of balance wheel. The bed measures 12 inches long by 6.5 inch wide.
Of the machines surveyed 4 reported to be low shank and 2 reported to be high shank. (Editor's Note: It is my belief that all 128s are low shank machines.) 4 machines had a light in back, 2 had no light.
All were portable in bentwood cases measuring 17.25 inches long, 8.25 inches wide, 11.75 inches high.
The 128 threads from left to right.
