[Milsurplus] Jones Plugs

[mac]

My 1944 Radio's Master lists "Hoard B Jones, Electrical Connecting  
Devices" as offering the 400 and 500 series connectors along with  
Series 101, 201 and 202 plugs and sockets.  Also lists lines of  
terminal strips (barrier and other) and fuse clips.  No address or  
contact information provided unfortunately.
