I know for sure that all of the 4th Fighter Group Tbolts had 6 guns.
This is an example of a 6 gun 47. If you look closely you can see that the outmost gun ports are covered. No idea which particular fighter group this plane is from.
The six gun option was probably more common with the earlier variants of the Jug considering they had a more immature version of the engine, not sure about the details though. :S
My only real gripe with the Jug ingame that the 3d cockpit is subpar compared to all other examples.
DT should at least try to retexture/replace the gunsight, that orange blob is just plain ugly.

Could you link to that discussion please? Many thanks.
