[Milsurplus] Navy shore radio station manuals?

[Nick England]

I'm interested in equipment used in Navy shore radio stations in the
1950's-60's.
The manual for the CU-168/FRR receiver multicoupler has a diagram showing
antenna cabling for a typical receiver site and mentions NAVSHIPS 91047 as
reference for "AF and RF signal distribution unit".
Has anyone got one of these manuals, or know anything about it?

Also mentioned is NAVSHIPS 91500 for the AN/FRA-3 RF Switching Group. Any
info on this equipment and anything else related to Navy shore installations
would also be greatly appreciated by the undersigned.

thanks,
