Looking for a part for an Old blind hemmer machine. It says: The New Dearborn Model O (or Q or 9--Can't read the print) and on the top is a stamped piece of metal that reads S5426. The part I need is the Looper. I purchased a part that was similar, but would Not work. Any ideas where I could find the part? Attached is the picture of the part I need.
