This late WWII aircraft was the fastest piston engine fighter of the war.
Heinz Nowarra's book "DORNIER DO 335 "Pfeil"" is about the same length, width and weight as a Squadron/Signal publication but that is as far as the resemblence goes. It consists of little more than a number of black & white photos of the DO 335 with a few line drawings and on cutaway diagram that must have been greatly reduced from a larger image because it is hard to decipher. There is a small amount of commentary but no camouflage & insiginia guides found in the Squadron/Signal books. ( )
