I haven't looked at a ZB-1 manual, but the "beaded" cables of that era were sometimes built like these at https://aafradio.org/garajmahal/DU-1&2_coupling_cable.html - came in both straight and 90 degree versions.  They are replicable with some effort.  Do you have any of the cables or male connectors?

I did just get a copy of the USN manual for the ZB-1. Only thing obviously different between the models is the coax connectors on the ZB-1 versus the other models. ZB -1 used what looks like a version of the “N” connector connector on the ZB itself and the switching relay

I may have misremembered this, I think the problems were more of a
sunrise/sunset issue rather than day/night. I'm going to have to
find the book and reread it.
