Most of the Singer feet have numbers on them. Sometimes it is really hard to find or read them. I have a list for the attachments that generally came with machines. The numbers are the same for the domestic 1
5s, 66, 99, 101, 115, 127, 128, 201 and 221 (FW). There is a difference for the narrow hemmer. I think I figured out why some use 120842 and others use 120855. It depends on which direction the thread is threaded through the needle. In addition to the narrow hemmer, the attachments that came with these machines would be the multi-slotted binder, the edge stitcher, the gatherer, the adjustable hemmer and frequently the ruffler (I think that sometimes the ruffler was an optional item or could be had for additional cost).
Most of the instruction manuals for these machines had the instructions for the basic attachments. Most of the manuals for these machines can be downloaded from
https://www.singer.com/support Please note that the instruction
manual for the 115 at this site is not for the 115s that were made from 1912-1935.
Lots of neat attachments and fashion aids were available for the old straight stitch machines. Most will work with any of the
models listed above (
in green). I did read recently that the pinking attachment would not work correctly for the 101. There is a neat booklet put out by Singer in the 1950s that shows how to use attachments and fashion aids. I believe the booklet was part of the "classes" that came with the purchase of a new sewing machine. I found a pdf of it at
http://ismacs.net/singer_sewing_mach...rence-book.pdf The Smithsonian also has instructions for various feet for sewing machines at
https://www.sil.si.edu/DigitalCollec.../sil10-218.pdf This one has the feet that came with adapter so one could change the feet without unscrewing the thumb screw that attached to the presser foot bar. It also shows the "bias cutting gauge" on page 10. I tried it years ago, but had a hard time finding scissors that it would work on. I wasn't impressed.
