My understanding is that the British set was completely re-engineered for
U.S. production, resulting in perhaps the first item that could be
considered "plug compatible".  Somewhere I have a picture of the original
British set (from Electronics magazine) and it is quite different
internally from the SCR-522 but physically the same outside.  This is
certainly a case of the AAF telling the Signal Corps that they should
just duplicate what the British already had, whild the Signal Corps
insisted it had something much better under development.
