Ok, I brought it in to take the pictures, oiled it up again and gave it one last chance. For some unknown reason, it has decided to behave and sew! It's a 603 and not a 600 like I had thought, still have the chain stitch thingy. So, it gets a reprieve and back to the sewing room it goes along with all it's attachments. I still have a box of the the funny flat (non-hat shaped ) cams left - not sure which machine they go to.
