[Milsurplus] Navy shore radio station manuals & info wanted

[Nick England]

I'm looking for NAVSHIPS 91047 which covers RF and AF Signal Distribution
Units for Navy shore receiving stations. 
Also looking for NAVSHIPS 91500 covering AN/FRA-3 RF switching group which
was used in these installations.

Army TM's seem easy to find, but I'd appreciate any suggestions about how to
find Navy manuals like this - is there a library that might have them?

Any photos or info at all on Navy shore receiving sites would be greatly
appreciated.

Ditto for Navy shore transmitting stations.

What I have so far is posted at

Many thanks,
Nick
