I think the stuff on top of the Boxes in the second picture is for a knee lever,but not sure, I am going to go back up and get all the rest of the machines, see what runs and what dont ,how many have feet and pedals . ETC and then sell them , and what is left will go for parts. Thanks for bearing with me on the pictures, hahah I had to rename the file etc to post, but finally made it. Meanwhile my husband had a major stroke, and now paralyzed on one side. home in a hospital bed, so my quilting is going to slow down considerably. CMARAS1234
