therefore I suspect the initial ZC 14116 is for the 2 prong plug with;
ZC 12795/10 for the clamped 'Y' fitting.
Dipole for a radar?

Co-ax pretty much came in with WW2, the UHF and Pye connectors were pretty much standard until things 'improved', with larger/heavier connectors for external use or field equipment. (e.g. Niphan connectors on army radio where the connection needed to be watertight and be assembled with wet/muddy/gloved hands.
Early radar operated at surprisingly low frequencies! The early sets operated on 54 - 84 MHz, SLC (Search Light Control radar was I think around 160 MHz or maybe 400), and so aluminium tube dipoles and small arrays would have been the order of the day.
