Hi Nick,
Thanks very much for your continuous efforts and generous sharing for a decade, this website of yours is great.
Regarding your Nachtjagdstaffel Norwegen article, below photograph has recently been auctioned on ebay,
http://www.ebay.com/itm/281582548112. This Ju88G-6 was apparently captured at Flensburg and displays a black starboard underwing as well as the white spinner spiral, similar to other aircraft of that unit. The fuselage is camouflaged with heavy Wellenmuster, again, a feature apparent for example at Bf110G-4 B4+KA or Ju88G-6 B4+SA.
Close examination does unfortunately not provide clarity, but the aircraft might carry B4+AA marking. The IWM has a photograph where the tail of our subject is visible behind a Ju88A and it supports at least the +AA interpretation.
Kind regards
Mathias
