I just bought the same model, 66 red eye, yesterday at an estate sale for $40. It has the treadle cabinet with it, but both the cabinet & machine need to be cleaned good and there are minor repairs needed. I've spent a little time online looking up the year of mine, which is 1919. Some prices I've found online for this model can be as much as $400, maybe more depends on the condition. If yours doesn't have a treadle it may be difficult to sew with one hand and turn the wheel at the same time with other hand. Just my thinking on it. Let us know what you decide.
