Peter:
This a/c is pictured in "Bf110 in Color Profiles" of J.Vasco and F.Estanislau. It is Bf110C-2 (with modified gunner's canopy central section), 3U+DD of Stab III./ZG26, Battle of Britain period. Fuselage sides overpainted in RLM65 Pale Blue. A/c #7 and #8: Bf110, 3U+B?, 4rth sign is unreadable, "B" seems to be black outlined in white. Camou - 71/70/65. So it could be possible 3U+BN of 5./ZG26 or 3U+BS of 8./ZG26, 1940.
