Back in the mid 80's I bought a house and discovered an old Singer sewing machine in the attic. The motor was bad and there was no info with it at all.
A recent TV program made me think about it again so I got it out and started some on-line research. Well the machine is a model 127 and was made in New Jersey in February of 1916.
Armed with this info I ordered a new motor/foot switch, drive belt, and lamp. The unit appears to be in good mechanical shape. Still need needles and bobbins. Perhaps convert it back to a treadle unit if a cabinet can be found.
I have the same machine also, mine is treadle only tho and made in 1923. If you search Ebay, you can find a manual and attachments for it and just about everything else it made need. They are very common and really neat machines
