[Milsurplus] Jones Plugs

The answer may depend on how you define "Jones Plug."

 

General Radio used a connector very similar to a jumbo-sized Jones plug in
connecting the external power supplies to its signal generators in the late
1930s.

The main difference was that it had a round locator pin in addition to the
familiar two rows of rectangular contacts.
