Hi, all!
I represent the next work - Messerschmitt Bf-110G-4, 7./NJG-6, Hauptmann Wilhelm Johnen. This kit - Eduard, Profipacк. Also used "Lichtenschtein" by Master-model, MG-81Z - Vector.
Yep, seen those on SN-2 equipped aircraft, but all G-4 with Lichtenstein I've seen have the single wire. I seem to recall having this confirmed, during my research when building mine, way back for the first GB.
