Seeking (old) N&W Signal Dept "Nomenclatures"

[nw-mailing-list at nwhs.org]

Anyone out there in List Land have access to the old (original) N&W "signal 
nomenclatures" ?

This would probably be a two or three page typed list of the abbreviations 
used for "nomenclaturing" (designating) the wires, relays, etc of the 
signal system.

I'd love to get my hands on the old nomenclatures... 1930s, 1940s or 
1950s.  Not interested in anything modern !

Thanks.
