Dusty'sMomma that it one of the 1st sergers that BabyLock made, at least 25 years old maybe more. They take special needles that are very hard to find and repair costs are expensive. It is a differencial feed machine and a pain in the you know what to thread. If he finds someone to sell it to that can repair it don't think they'd pay over $25-30 for it. He could just try to list it on E-Bay as is or for parts.
