as promised, I checked and the Trumpeter has indeed the P-36/H-75 elevators. You will find here plans comparing them:
And here is a TM view of the correct elevator shape:
I also found that old analysis made by Steve Gallaci. It explains the weird shapes issues I mentioned:
I have the Craftworks kit as well and the shapes look better even if, as Iain kit showed it, the Chinese kit LOOKS like an early P-40. Moreover, that resin kit is a true dog to build. I guess that comparing pictures, plans and the Trumpeter, Craftworks and later Hasegawa P-40 kits is probably the best way to get the final word on that.
I hope this helps.
