The trouble with the Roman numerals is that they can be misread, particularly in the case of II Squadron. It is reasonable for the layman to ask is that two or eleven? CXX is a mystery to most of us who haven't had the benefit of a classical education!
As for squadron 'crests', I referred to them as such in a letter once. I received the mother-and-father of a bo***king from a senior. I have always referred to them as BADGES!!!
