How do I identify the model of my old Singer?
Go to this link and you will see a pictorial flow chart to help you identify what model you have: Sandman Collectibles
One of the best resources available is ISMACS. To date your machine with the serial number go here: ISMACS serial number data base
Again, ISMACS has many free manual downloads. (If you want an original manual, check eBay.)

There are lots of resources, but here are three I've used frequently. They are all reputable dealers and carry most parts you will need to fix up your machine. However, for parts like missing slide plates or face plates or any other ORIGINAL parts you need, go to eBay. People part out machines all the time, and that is where you will find an original replacement (rather than a reproduction.)

I have a post about most of the attachments in the LITTLE GREEN BOX. Also, all the old manuals will illustrate and explain each one. If you don't have a manual, there are free downloads available (see above.)
I have a post about the SINGER BUTTONHOLER which explains slant shank versions versus low shank versions. These are easy to find on eBay, and not too expensive. If you have a vintage Singer, you really must get one of these!
Check out my post on the SINGER ZIGZAGGER. This is a gadget that will make zigzag stitches on your straight stitch machines and comes in both low shank and slant shank versions - they are available on eBay.
