Up for sale here is this used vintage set of wires, with an octal plug at one end and an octal socket at the other.  The plug is a Cinch and I'm guessing the socket is as well.  Both the plug and socket have metal covers over them.  The wire is rubber or plastic-coated, not cloth, just FYI.  Probably a few feet long.  The plug and socket have plenty of wear but will work fine.  Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
