I have three attachments which I bought together that Ave Simanco on them along with a 6-digit part number. Two are hemmers, one marked 3/32 & the other 1/8. The other is a ruffler of a type I have never seen before. All three of these have only a hole to secure them to the presserbar & lack the slot for sliding out the side. I believe these to be industrial attachments. Also, the drive arm on the ruffler is on the wrong side for the #9, D-9 or 9W machines.
I also have a near-complete set of attachments in the D-9 configuration, including the side slot on the shank, same side as the D-9. These have six-digit part numbers on them all beginning with 225,xxx. I believe these to have been Singer made for the 9W machines, but will fit the W&W D-9 as well.
