Some questions...
1. Photo reference?
2. What template used? Jesters?
Cheers!
P.S. Shark mouth of III./NJG 3 does not mean that all Bf110's were used in II./ZG 76 before... I have phtoes of Bf110F and G from III./NJG 3 with sharkmouth

Also, emblem was modifiyed in 1944.
Actually, after II./ZG 76 was trasformed into nightfighter role, it just kept its emblem. That is true reason.
