Of course the vertical convergence is relevant for all guns, wing or fuselage mounted.

One needs it to adjust the point where the ballistic arc of the bullet and the sight-line intersect.

ah, ok.. of course. I'd overlooked that.

Referring the aircraft.ini, iL2CoD-v1.05.15950, the standard convergence for all BF109E is defined as follows:

nose mounted MG 2x Rheinmetall-Borsig MG 17 (7.92mm)
vertical convergence == 400 m (Visierschuss)
horizontal convergence == 420 m (Kreuzung)

wing mounted MG 2x Rheinmetall-Borsig MG 17 (7.92mm)
vertical convergence == 500 m (Visierschuss)
horizontal convergence == 300 m (Kreuzung)

wing mounted MG 2x Oerlikon/Ikaria MG FF (20mm)
vertical convergence == 500 m (Visierschuss)
horizontal convergence == 300 m (Kreuzung)

wing mounted MG 2x Oerlikon/Ikaria MG FF/M (20mm)
vertical convergence == 500 m (Visierschuss)
horizontal convergence == 300 m (Kreuzung)

There is a good reason why vertical standard convergence is 500 m (Visierschuss). The German iL2CoD munition types have been animated in a version "verbessert" (improved). The cartridges are of high-velocity type for maximum performance in aircraft machine guns and give higher pressure than other 7,9 mm rounds.

... and here are the standard convergences for all iL2CoD Spitfires and Hurricanes, taken from aircraft.ini, iL2CoD-v1.05.15950:

vertical convergence == 370 yards
horizontal convergence == 370 yards

That's great info, very interesting, but I hope no one takes these values and tries to translate the numbers to in game. With all the Tom Foolery going on with the inaccurate flight models, I'd be extremely surprised to find out that ammunition was correctly modeled in such a fashion as listed above.

Which makes them converge horizontally at both 200 and 400 - just as a HK G3 assault rifle with the sight set at 200 meters is also correct at 30 meters with the bullet passing the sight line "on the way up" (remember that from my military service days ;)). Not that it matters much at 30 meters but when calibrating sights you do that at 30 meters as it's easier and then it works for 200 meters too...
