it did have 4 kills at the end of the War so it must of seen some action
There are no records of any kills by a Do-335. The only official Allied account of the encounter was at the hands of a French ace flying Typhoons when he and his flight encountered one at low altitude. The Typhoons then dove to intercept the Do-335 only to have the Dornier turn and rapidly accelerate away, the Typhoons never got within gun range.
Besides, the Do-335 never saw operational service nor did it enter into production. Only around 13-15 preproduction models were built before the Allies overran the Dornier factory.
If there are any Soviet records of any encounters they've had with the Do-335 then they must be still keeping them as state secrets because there aren't any official reports of Soviet pilots ever encountering a Pfeil in combat.
