I just bought a used Necchi lock serger without the manual. It has three thread cones and appears to be in good shape. The person I bought it from did not have a manual so I have researching it online. I see all kinds of references to the Neckchi sergers but can't find ANY information about them. Is anybody out there familiar with this serger? I have spent several hours researching and can't even find a picture even though it the link advertises them. I would appreciate any information about this little guy!
