I found these in a box of attachments given to our 8th grade quilting class...they are low shank, side clamp, but don't know if they are for old treadles (I kinda think so cuz of the ruffler) or old singers. Did Singer make any low shank machines Billy? If anyone needs them let me know. I could get get them in a $5 postage box. Just reimburse for shipping. No name on box either.
lots of pieces
