[Fists] Origin of 'ES'?

[Will White]

Does anyone know the origin of using 'ES' for 'and' in CW? Obviously, it is
shorter to send, but why not the Spanish 'Y' or French 'ET'? It *looks* to me as
though it is derived from another language, rather than a contraction or
abbreviation of English, like GUD for good or ABT for about, but who knows. ANy
ideas?
