In this interesting JG 77 colour video, there is atleast three Focke-Wulf licence built BF 109E-1's: WNr. 4065, 4067 and 4085.
(WNr. 4 001 - 4 090, Bf 109 E-1, Focke Wulf Flugzeugbau, Bremen)
JG 77 BF 109 in 1939
Focke-Wulf used rounded edge Werkenummer-plates and those can be seen in video 5:22 ja 6:07.
One FW built BF 109E is still around and under restoration and that is WNr.4034.
