Not MG151, only MG/FF. Not nearly as effective as 1x 20mm MG151/20 in the nose, but hey I wouldn't argue for that plus the nose gun (yeah, yeah, I know, rare, 1 plane only, not standard, etc, etc)
What I really want is the twin MG151/20 pod under each wing for the 190A-5 and A-8. Relatively rare, but I'd love to see it on the JG11 A-5 skin (which historically flew with it!). Weight/drag penalties would balance out the increased firepower, but still it would be damn cool for bomber hunting!!!
