Thanks for the links Berthier.

I have downloaded the Popham Signal Code to add to my other code books, Imperial German, Kriegsmarine, RN 1916, all photocopies and a 1935 International Code of Signals, a German 1966 International Code, and the current International code. I refuse to asnwer how much it cost me for the photocopies!!! I did have to colour in the flags and coloured light signals in them though.

I can see why they went from a numerical code of 4 flags to a letter code of mainly 3.

My main thought about signalling was for the "Admiral" to direct his or her ships, not for individual ships to chat. That would only need a mast positioned where the "Admiral's" ship mat would be located. All the other ships would need would be an "Answering Pennant." Use the current one for that. As for signals, the only ones needed would be for indicating direction, and engaging or disengaging combat.

Cheers
