ⓘ What is a Documented Machine?

A documented machine is a surviving Singer sewing machine that has been examined in person and documented by a collector, historian or enthusiast.
Alongside the information provided by the serial number, we add details that can be identified from the actual machine, including decals, variations, and model versions.
These real examples help us compare historical records with surviving machines and improve the accuracy of our database.

ⓘ Where do I find the serial number?

The serial number is made only by numbers, and it can have one or two initial letters. No dashes, no spaces. No letters in the middle nor at the end.

The most common places to check:

On top of the bed: often near the handwheel side, either at the front right corner or sometimes at the back right corner.
Underneath the machine: check the bottom edge of the bed, usually on raised metal pads or flat engraved areas.
Near the bobbin area: some older machines have the serial number stamped on the throat plate (the metal plate covering the bobbin area) or underneath the slide plates.
Less visible areas: some models may have the serial in hard-to-spot places underneath the bed, usually on a raised metal pad. Do not confuse it with part numbers, which are usually not stamped on a raised pad.
