My repairman says if it is old and does not have plastic parts it is worth saving if possible. I have 15 machines and if I find a machine that is not going to be easy to salvage I donate it to my repairman who is very reasonable to repair machines..He appreciates any parts that are hard to find. I never know when one of my old machines might need one of those parts...He has always been able to repair what I take in.
