I know what you mean that some Japanese WWII planes were Oscars, Hayates Rufe.etc but they were just called Zeros by allied pilots.
same for the Russian jets which although could be Sukhois or Yaks were simply called "Migs". This was the case with the F-14 downing of 2 Libyan Fitters which the press initally reported as being Migs whether specific or not
