What we have is a Singer 29K58 Cobbler's sewing machine in excellent working condition. 29K4's are easy to find, but the 29K58's are more difficult to come by. It's a later model so it has coil springs, not flat springs like the earlier models, which makes it much easier to make small adjustments. I've replaced the rubber wheel on the bobbin rewinder. Included is the wire for threading the machine, 8 bobbins and assorted needles. The K-58 will sew light to medium leather, about 3/8 inch thick. The heaviest thread it will take is 138. This machine works great and has performed perfectly for me. It runs smoothly and turns effortlessly. I've used this machine for light leather work such as bridles and chaps. I find that I just don't have the time that I used to and the machine is not being used as it should. All sales are final so please ask any questions before bidding. Thank you!It includes the instruction manual.
