I bought my one and only Huskylock in the early 1980's, so I guess that would make it vintage. I still use it when I need to serge something. I run it three thread most of the time, but it will take a second needle for a locking stitch. If I want a narrow serge, I can remove the outer needle and tighten up the underloop, shorten up the stitch length and get a really nice, narrow embroidered looking rolled hem. Works great for things like bridal veils.
