Abram,

Here's a nice example of what you're referring to regarding three 
complete arms as shown in 'Norfolk and Western Railway Modern Coal 
Burning Steam Locomotive'.

Please do find the photo you're referring to.

(The obbious reason behind this type indication is that the signal 
engineers were using rows of lamps to replicate the positions of the old 
semaphore arms. There also exists at least one photograph of an N&W PL 
signal which had three complete arms, each represented by a full-circle 
background. In the photograph, all three arms are lit at STOP... AND 
there is a single-lamp "Marker Light" under all of these. If anyone 
wants the photo, perhaps I can find it.)
