Signal question

[NW Modeling List]

I'm JUST getting to the signals part of my 1930's era layout, and have  
been looking for the drawing of the Block Signal, especially, the  
height of the signal heads above the rail. I'm doing a generic  
Southwestern Virginia look about 1934-1938.  It's a two track all the  
way around with just a few sidings, all manual.  I have several sets  
of single track crossover, some right to left some left to right.  I  
will most likely use a rotary switch for the lights, but didn't they  
use both Semaphores and Block signals together?  As you can see,  
signals are my weak area.
