Mast Base AB-15/GR - what is the name of this connector

[Constabulary]

I have seen AB-15/G mast base with 2 different "antenna cable connectors"

One is the UG-273/U for the coax cables.

But by the lord I cannot figure out what the name of this connector is.

This is the one where the antenna wire is just clamped with a thumb nut (kind of).

 

Can someone help me please

If someone has an AB-15/GR with the above shown antenna cable connector / adapter could you please check if there is a parts number stamped on? Drawing does not show the parts number. But I know the UG-273/U has it stamped on.

I checked mine. It has no markings.

Does some one know where to get spares? I mean there must have been replacements, I don´t think the Army junked the mast bases when just a connector is smashed.

Any chance that this is available as a civilian part? The UG-273/U is available as civilian part but I have no idea what to look for.
