The oldest one I've ever come across. Procedures for installing cables and maintaining related equipment.
Very nice! and in a handy little book too. :)

I don't plan on installing any telephone poles any time soon so I figured I'd let it go. I have another one from 1929 that covers PBXs.
The cables are buried nowadays.

The long lines are wireless as well.
I also have a 1929s PBX BSP from N.E.T.&T.
