This is for a WW2 Air Ministry/RAF Aircraft Cockpit Flying Helmet Jack Plug Socket which has a stores reference of 10H/2206. It is used and in good condition for its age as can be seen from the pictures. I currently have a number available, The pictures show a selection of them. They all come with the 4 connectors, some are missing there metal finishing loop which sits on the socket end (some in the pictures have them and can be seen). Thanks for looking.
