What are these vintage Pfaff feet?
 

These are from the early Pfaffs like the 1222. Anyone know how they're supposed to be used?

The foot in the top photo seems to be a 1/4" seam guide. The lower left one seems be a shirring foot. The fabric would be fed thru the slot and depending on the stitch length would gather the fabric; i.e, the shorter the stitch, a tighter gather and the longer stitch obviously would be looser. The lower right, a stitch-in-the-ditch foot (?). The screw on the top lends to being adjusted.

Just my guesses! I am anxious to see what others think.

I think the top one is a piecing foot too. I've since been told the lower right is a blind hem stitch foot(also stitch in the ditch I would guess). The shirring foot sounds correct too. I wouldn't have a use for that one!

Aren't these people knowledgeable? Love them all!
