Nice big load of hogs you have here
I feel I can help Re the RNZAF bird
No kiwi Corsairs had yellow surrounds on the wing roundals
NZ5339 had no tail codes, and its nose codes though placed correctly were hand painted and underlined I can scan a pic of that for you.
The yellow surround on the fuselage roundal stopped at the white of the bars
and the blue centre was smaller than your version.
Its had at one time a yellow prop dome and had full tape on the fuel tank seams
(Later it was painted over to looks like yours but with overpainting marks and had its dome changed to red)
Although correct this aircraft did one time serve with No22 Sqn its more correct to label it No31(SU)
RNZAF fighters belonged to servicing units and were 'loaned' out to squadrons, NZ5201 for example was used by 11 different RNZAF squadrons
