It doesnt matter how many times you tell something again and again: the truth remains the same.
This aircraft never been in operational service, nor have been sent out to the squadrons.
Would be better to ask for something what
-fills some kind of hole in the planeset, -the Do-335 doesnt fills any hole, being something simmilar to the 152.
-seen service, was produced in numbers and -the Do-335 wasnt produced in big numbers, never seen service
-had a real role in the war. -it had really no role in the war, being more like just a handful of prototypes.
There are many choices what fits the criteria 1000 times better than the Do-335, being core aircrafts of the given country:
Ki-43 and -44, Jak-3 and -7, Tu-2, Pe-2, La-5 (early model), Ju-188, Do-17 and -217, FW-187, He-111, Ju-87G, Beaufighter, even the Whirlwind or the SpitXII.
Possibly missed out a couple. Anyway, your fight is pointless and wont lead anywhere. Salute
