Hello everybody, I was reading "Divisional Signals" from the free, online New Zealand WWII text collection (CORPS LINE COMMUNICATIONS TAKEN OVER BY NZ DETACHMENT — (WESTERN DESERT FORCE SIGNALS) ON ARRIVAL BAGGUSH, 10 JUNE 1940 | NZETC) In there, I found a line diagram showing the communications of the Western Desert Force in 1940 which I have attached in this post. My question is related to two symbols whose meaning is unclear since they are not included in the legend. The first symbol is a white arrowhead which is found at the end of some lines The second symbol is again a white arrowhead with a short straight line at the top. Does anybody know the meaning of those symbols? Thank you
Pamak, As a retired Telecommunications engineer & 2NZEF researcher, your query intrigued me. The key to the diagram is in the legend "Fullerphone" This is a telegraph device used by the military. Uncle Google provides a link to the website "Wirelerss for the Warrior @ Wireless for the Warrior - The history of British Army radio There is an awesome amount of info on this site and a contact who I am sure will be able to answer your question. I should know and looked up some old textbooks but can not answer it at this time!
Thanks for the reply GeoffMNZ, but if you actually notice carefully, the symbol for the fuller phone is not any of the symbols which show a triangle The fullerphone symbol at least in this diagram is a short straight line perpendicular to the end of a line connection making the end look like a "T" . On the other hand, the symbols of my question are either a triangle of a triangle with a short line at its tip and they are omitted from the diagram's legend. See the attached image in my first post.
Here is the legend of the original line diagram Notice the absence of any symbol resembling a triangle
As I said, I am sure the website authors will be able to help you if you contact them as they are experts in Military Signals.
Update: I got a very quick and helpful reply from the website author Here is the legend with the symbols from a pre-war manual
