Thank you for all of your information Charlee! That is so very helpful. Especially the buttonholer, I wasn't sure if it would fit ANY of my sewing machines! I'm thrilled to know it will work on my 221.
Believe it or not, I was tooting around in my sewing cupboard and found another box of attachments I didn't even know I had. Mosty hemmers and another ruffler. I will take pictures if I find anything that hasn't already been posted.
Also - the skeleton key did not fit the treadle. :( SO SAD! LOL* There are key holes there, but no key.
OH - and Charlee - that IS a Singer shuttle? I found another one with the old fashioned long bobbin in it with thread on it even. So those are for a Singer and not my Sears and Roebuck? I do have a Singer Treadle, but it doesn't take the long bobbins.
One more question - oiling the ruffler and buttonholer, how often should that be done?
