Hi all you experts. I bought a White Rotary Sewing Machine yesterday, Serial No. 45X81196, I believe the model is 9801-4. It is a brown crinkle finish in a nice cabinet. I took it apart to clean and oil and now I can't figure out how to assemble certain parts. Would like to find a manual for it and also tips on assembling the take up lever and tension guide spring thing. Any and all info will be greatly appreciated. It is so different from all my other vintage machines. I didn't take pictures before I disassembled as you guys and gals advise us to do. My bad.
