Does anyone have a Singer Manual Pinking Machine
 

I came across a small instruction booklet for one today while looking for something else. Looks like the model # is 121379.

I do not own one now, but I have owned both the crank pinkers and the ones that are a sewing machine attachment (obtaining their power from the needle bar similar to how walking feet work). My understanding that either a pinking blade or a plain blade similar to a rotary cutting blade can be used in the units. They are very fascinating!

I have one but it is #121369. I don't have the box, clamp or instructions for it. I wonder what the difference is between 121369 and 121379?

I have the 121379 with the machine, box and manual sitting right behind me. My Mom found it for me.
