Spanish signal flags (set of 1-20)
A grid system with the 20 across the top and down the left side, gave 400 combinations for the Spanish signal code.
Flags and codes were used in conjunction so that the meaning of signals could be changed at intervals – particularly when codes fell into the hands of the enemy.
The signal flags have been researched by Rod Langton and printed to be correct for a specific point in time. It is extremely difficult to be precise about the meanings of particular combinations, so none are given here. However, signal flags greatly enhance the model and are highly recommended for a quality finish
