Oooh! We believe these to be around WW1 timeframe from the uniform silhouettes. A complete set of training/reference cards showing the physical demonstrations of each semaphore letter, together with its verbal equivalent and morse code translation, plus descriptor cards. This is a rare set in that it is both old and complete. It is unboxed (if indeed there ever was a box). Each card has age appropriate wear, with the letter X looking a little chewed.
Perfect for the enthusiast or would look beautiful if framed.
