Does the nose gun rotate the nose dome like Lyric posted all of that info on some time back?
Parts are missing that I see.
No mounting bracket for the gun.
No gun cradle that the gun bolts into.
No belt feed ammo chute either.
Essentially it is the KI-67 prototype gun by appearances.
If the only pivot point is the point of the Plexiglas nose it is the same as what we have now.
Best guess very limited range of correct gun arcs.
Sadly no screen shots of the tail gun to see what is going on there.
