We had junk night in our town and I found this sewing machine. A 604 Singer. It did come in a cabinet and we took it out of that. It seems to run fine except, it won't move the the fabric under the presser foot. The feed dogs are up. It didn't have a bobbin in it and not sure what kind it needs. Also noticed there is no place to wind a bobbin. It also has the words Auto reel on it. Can anyone help me?
