Vintage Lot: Singer Presser Feet - Ruffler, Multi-Slot Binder, Hemmer... w/ Box!

Description

This vintage Singer box contains six vintage Singer presser feet though I do not know if they are what originally came in the box. I believe they are all for low shank machines, but are being sold as vintage collectibles since I do not know for certain nor do I know if they will work with modern sewing machines. Four are marked "SINGER USA" and two are marked "SIMANCO." I do not know for certain which year(s) they are from but my estimate would be the 1970s. The presser feet included are:
Ruffler Foot (SINGER USA 120598)
Multi-Slotted Binder Foot (SINGER USA 160359)
Adjustable Hemmer Foot (SINGER USA 35931)
Edge Stitcher Foot (SINGER USA 36865)
Gathering or Shirring Foot (SIMANCO 121441)
Hemmer Foot (SIMANCO 120842)
The box is in very good condition for its age with significant wear and scuffing but no split seams or tears. The presser feet are also in very good condition for their age with a little discoloration on some, but I do not see any rust. Please see photos for better idea of condition and ask if you have questions as I have no sewing experience and may not know what to look for.
