For the fun of it I also have links to reproduction fabric wrapped electrical wiring. I've "kinda" been looking for a complete machine ( complete with all the original connectors ) to rewire. Or, a set of Chicago plugs to use on my Free Sewing Machine Co.
Long Bobbin Rotary that was jury rigged eons ago. If I could get a good set of those plugs I'd rewire it as the OEM wiring was.
