Thank you for info, FD.
Unfortunately I can't read japanese, therefore I'm not able to understand what's on the page you linked.
As for now I know Hasegawa (japanese scale models producer) having such aircraft (with clover) in their catalog. I own myself the 1:72 scale of it. Hasegawa is usually pretty accurate.
Moreover the design of the clover seems to me much closer to japanese aesthetic style more than to american one.
Of course this is not enough to document the skin as "historical", therefore I will make some more researches about this. Any help is appreciated.
As for the Hien-Tei models i think HTC posted somewhere that they have some tollerance between very similar models (I remember it was about the Spit Mk. VIII, whose skin is accepted even if applied to a Mk. IX). Therefore I hope this not to be a real problem.
Thank you all for feedback.
Best regards
