The Zwilling was a proposed fighter/interceptor aircraft by Messerschmitt for the November 1942 Schnellstbomber competition, only to be beaten by the Dornier Do 335.
With a top speed of 435 mph, its one of the fastest out the 109 family of fighters, albeit not even built.
As I own the beauty in WT, and its such a unique aircraft, i would love it to be in aeronautica, if it would be added, it could be added for any other military/event badge, or sold as a Ultra Rare/Rare rarity.
Knowing that the BF-109 is already in Aeronautica, i would believe it would be a modification to the already existing model.
