BECC Flags: International Code Signal Flags
This code was used by the majority of the world's nations since 1837 and the British navy since WW2.
The code comprises 26 Letter Flags, 3 Substitutes, 1 Code Flag and 10 Numeral Pennants.
The signals are supplied in two sets; ICA (Set A) which has the more common flags and ICB (Set B) which has the remainder.
