Howdy from Farmville, VA! Yes, Farmville is a REAL place:) My husband is a cowboy from TX who enjoys leatherwork, he creates mostly custom tack for our roping horses and can repair just about anything to do with leather. His Singer home machine just broke and we just purchased an old industrial SEIKO machine walking foot and cylinder arm which I believe is a CW-1. It works well but has no paperwork with it. I have been searching for days to find a manual and to try and determine what size needles I should order and what size/type of thread. My husband is old school and did a lot of his work by hand. I need help! Any and all would be appreciated:) I have attached some pics of the machine in case anyone is interested or knows exactly what we have. Thanks!
