Here is my set
Three slide plate (race cover) 3/16", 1/4" and 5/8" hemmers,
Bed mount (shank) 1 1/4"
Bias Binder (mounts to the head)
Under Braider (has grove for different widths of braid)
Bed mount 1/8" hemmer
Gauge and Self Sewer
Ruffler
Automatic Scallop Plaiter
Tucker (mine was missing a screw and nut - got ones that fit now)
I also have the quilter (it's just a guide) though this one is different shaped them typical.
These is the complete set listed in the NVF manual I have - so you'll know what you are looking for. I see them come up on eBay occasionally, rarely listed as NVF though - usually just with an assortment of other attachments.
