Auto button attach/bar-tack, model 1903A. It is in fully running condition and currently being used in the factory. I need money, so I am selling it. Do not compare this with repaired shop machines. This is a running machine; if you buy a second-hand machine from a shop, you will have to spend a lot of money on parts and time to get it running. Since this is already running, it is a hundred times better than shop machines. Serious buyers only, please do not disturb. Call directly if needed.
