Ok, before I do the next update I wanted to go back and re-visit "Nicki"
After some further research it appears Nicki was in fact NF672 (572 not even being a serial used by the FAA it seems) and wore K onboard of HMS Nairana in 44 during atlantic service, as confirmed by Burgham's own log book.
now, if you Look at this photograph -every time I do it makes me laugh.....(sorry)
there's a few stand out features that have been debated about, what I initially took as shadow under the wings is in fact differing colour, it seems the White overpaint on HMS Nairana was indeed by request of the commander flying and in turn the captain of Nairana to the admiralty, but there wasn't quite enough offwhite paint to go around, so upper surfaces and leading edges/tailplanes were painted only, leaving the underside in it's factory Sky (known now as Sky type S).
Secondly you can see in the very far left of picture under the outer starboard cannon is a large black stripe, this picture was taken mid-late 44 and it is believed that Nicki wore Invasion stripes on her underside at least, though as you can see this does not extend to the leading edge so as to keep that front aspect clean.
The FAA was using white, and earlier sky grey to colour the undersides of their aircraft so as to camouflage some of their planes against the heavily clouded skies of the atlantic and northern theatres, it worked well, the only problem was that by the time a flight of stringbags (Swordfish) got to a U-Boat even with the camouflage it had pretty much gone under or even worse, by 44 the AAA on the bridge of a U-boat was considerable, some of the Type IX boats featuring 3.7cm flak guns, with several twin 2cm guns. The poor swordfish was slow and something of an easy target for these gunners, what was needed was an assault by fighter craft first to clear the AAA gunners and bridge crew and allow time in the confusion for the reliable swordfish to get her torpedoes or depth charges on target, this was the task of the Sea Hurricanes of 835 SQN as well as their general interception and fleet protection duties.
I'll be altering the Nicki skin shortly to change the colours underside and later i'll add the invasion stripes (still messing with the various overlay plates)
for those who want a fully white skin, i've decided to add another 835 SQN plane NF700, flown (and crashed) earlier by Sub-Lt Burgham, though she also had a sky under, i've put her in as all white as it's a rather nice look. This plane infamously crashed by Burgham in March of 44 (before invasion stripes) was on final, the ship pitched 30 feet in a swell just as the batsman give the cut engine signal and 700 was wrote off as the tail struck the rounddown:
With luck you'll do better with her, I'll update the main thread shortly, i need to redo my screenshots as i've updated all the colours and I finally have those Mk IX spit skins ready.
