Thanks for your response. Since I am far from being any kind of sewing machine repair person, I am not going to buy the old Singer patcher. I am looking for a new machine, or a good second hand one, which will serve my purposes. I am mainly going to make moccasins and mukluks. I don't know anyone who does leatherwork, so I feel fortunate to have found this forum!
