A couple of weeks ago I got some back clamping attachments and an assortment of things I didn't know what they were. I'm slowly figuring out what they are.
I got a long foot that is of a rougher texture and a different metal from the regular Singer attachments. It has a slit from the right and hole there for the needle, a larger hole and slit from the right, a slit and rectangle opening from the left and another rectangle hole and slit from the right. I didn't know what I had, but sent a picture to Sheluma. Thanks Sheila!!! She looked it up for me and found out what I have. I have a Dooley sewing foot that is supposed to do all kind of things.
I got the patent information for it, and then found the pdf for the instruction book for it. It is found here.

A neat attachment. Now to try it out on my Singer 66. The one in the instructions is top clamping, and mine is back clamping. I don't have the shirrer for it. Does anyone have one to spare?
