 From the N&W Rules and Regulations for the government of the operation 
department, takes effect April 1, 1945.

Page 205, signal indications for Block and Train Order Signals in 
Manual Block Territory
Blade Horizontal, red lens showing, Stop for orders, or block occupied
Blade at 45 degree angle to top, yellow lens showing, proceed under 
permissive block
Blade at 45 degree angle to bottom, proceed

I assume that these are the indications you are searching for
