Singer 29k71 Patcher is a very versatile machine. The treadle stand is missing.
If you know this machine then you know how versatile it is, helping you out of tight spots. Old they may be, but they certainly do a great job at fixing up modern day clothing. While the design of these machines has varied little from the ~1910s the machines can be purchased new today with near identical designs.
It is not easy to use, nor is it easy to set up. The bobbin is small and has a very limited capacity. Threading of the bobbin requires some learning, as this is unlike other machines. What is the purpose of the long wire?
