From a preliminary search, the timeline doesn't add up for Mk108 on the G-6 for Hungary. Most of Hungary's G6s were after mid-1944. They had some before then, but small numbers not counting the G-2s and the like.
However, even the Luftwaffe found it hard to get Mk108-armed Bf109G-6s into production until well into 1944. Even then they had a hard time making them enough for Luftwaffe units before they could devote resources to exporting them. That would have taken some time as well.
Our in-game G-6 is the 1943 version. It should not have the Mk108. Nor would it be representative of one if it DID have one. It doesn't look like Hungary got Mk108s until the end of 1944. A late 1944 Bf109G-6 upgraded with field mods is... in all but name... a G-14. The G-14 was the version that combined all the modifications into one package.
The G-14 is what Debrody needs to fly, to match what Hungary had late in the war. Otherwise the G-2 and G-6 are already accurate (for the most part).

Debrody & Gyrene: those posted production numbers are Luftwaffe numbers. Not Hungarian numbers. Read the first post here:
