Chain-Stitch Embroidery foot?
 

Is there a chain-stitch embroidery foot in this listing below? The foot in question is just below the oil can in the upper right-hand corner of the photos, the one that appears not to have a box. I've been lerking for one since last summer.

I believe that is a blind stitch attachment.

That is however, one heck of a collection for the price....

the funny looking unit that isn't in a box that is below the oil can is a Hemstitcher - it goes in the box right above it.

I don't know if I've ever heard about a chain stitch embroidery foot - unless you are referring to either the Single thread or double thread embroidery attachments, but neither of them are "chain stitch", they are looped or twisted around the regular straight locking stitch.
