Hi folks:

I have a copy of this 1920 book, and highly recommend it.  Very thick, and 
full of illustrations, wiring diagrams, and good poop.  Lots of telegraph 
info, of course, but also quite a bit of info on early teleprinter designs:

wheatstone perforator
hughes teleprinter
original baudot (piano-key) system
murray system
western electric multiplex
