Published by Bernards (Publishers) Ltd during the Second World War and recommended on its cover for RAF, Army and Naval use, this pocket manual teaches the methods of visual signalling that any serviceman might be called upon to use.Semaphore comes first, with the procedure for sending and acknowledging a message, the conventions for numbers, punctuation and errors, and a drawing of the signaller for every letter and special sign. The International Code of Signals follows, with its alphabetical flags, numeral pendants, substitutes and answering pendant reproduced in colour, and a worked example of how the substitutes are used.The Morse or International Telegraph Code is set out in full, with the alphabet, numerals and punctuation marks, the timing of dots, dashes and spaces, and practical advice on learning the code and building speed. A closing section explains the heliograph, which sent Morse by flashes of reflected sunlight.A compact and colourful survival of wartime instruction, this reprint will interest anyone studying military communications, naval and army signalling, or the everyday handbooks of the Second World War.
