It's just a straight stitch machine, so has a limited usefulness, IMHO. Do you need one? I'd rather put my time into one that at least does ZZ, and takes standard low shank feet, that way I have at least a slight chance that someone might actually pay money for it. There is no market for old machines around here and I usually end up giving them away. Folks who list old machines on CL for hundreds are dreaming. The situation may be different in other areas.
