Has anyone got a name for these coaxial connectors?

Background grid is 0.10in /2.54mm.

They're not MCX, MMCX or CRC9.

Were used quite extensively internal to RCA and other
video broadband RX/TX assemblies in the 60s and 70s.
External connections of the boxes was generally SMA.

I've used them in modular interconnect, inside chassis,
but am begining to run out.
