My dear husband picked up a Singer Model 99 from a garage sale this past weekend, serial no. AD94962. The poor little thing had been stored in a barn for several years causing mega rust, rotted domed case bottom, motor and cords all in very bad shape along with years of smoke and dirt buildup. The hand wheel would not turn. I always said I wanted an old machine to tear apart to see if I could get it up and working again - well I got one and love it. The machine now has all parts moving freely but I cannot serioulsy test drive it because I can only trun the wheel by hand. The question being can I convert this machine to a hand crank? I have looked on e-bay and not one hand crank is identified for a model 99. What wheel and handcrank style do I need and is there anything else needed for this conversion? Thank you for any help you can give.
