Impressive. Good work sorting out the different gun director assemblies like that.
One note though: a quick googling to find out how the early ECM looked like immediately turned up two different sources (pic from 1945.04.14)
where the "double cone
" name was assigned to AS-57
/SPR-1 instead of AS-56 and vice versa. Since both share the SPR-1 system name, how significant would that be?
