Trotting out the ol' Kugelblitz IV, I see!
Looks pretty cool and an interesting camo.
But, at risk of sounding a bit grumpy... your treatment of the turret versus kugel element makes little sense (to me)! I could guess that you, as I believe the Germans did, are creating the developmental Kugelbltz by putting the prototype (painted rot-oxide) turret onto an available Pz IV hull (which presumably could have been an in-service hull wearing whatever camo it had when "seconded" to the Kugelblitz development program). That is what history records them having done.
The outer "socket" element of the turret was just as new and developmental as the inside "kugel" part - and the two parts came as a unit... so I would expect that both parts would either be "new, un-finished implants" and both in rot-oxid, or both would be "seasoned implants" and both painted more or less to match the hull... Why the outer turret would have been painted but the inner left red is what I find weird!
It's almost like you are "suggesting" that an in-service Kugelblitz (fully-painted) had a last-minute swap-in of a replacement kugel!
Just saying!
Build on! These always look cool, to me!
Cheers!
