So far as P-40 kits are concerned, what are your favorites? In 1/48th, E or later? I figure Hasegawa by a head, followed by AMT, Mauve (gone) and then the Otaki/Arii and the Revell/Monogram update. I see that most are now on the second hand market, at that.
I started out with the Aurora, so I see nothing but improvement, regardless.

Bernard this is my 10th P-40 I've built that I've kept for display...Two Monogram/Revell, one Academy C model and the rest are AMT's. Mostly E models but I did do one F, one K, and one N. I believe all are posted on this site. Early on two Monogram P-40B's were used as test beds for my newly required old hobby. They were given to my grandson and were promptly destroyed in aerial combat.

Haven't done a Hasegawa yet but have an E and a N model in the stash. The detail in those kits look really good. Haven't done nor do I have the new Airfix kit so can't comment on it's construction. I really enjoyed taking the old Monogram P-40B and adding the Medallion Models upgrade, from Mark's Models and Toys,, plus some wheels and a seat and it really produced a nice looking model. So that's my story and I'm sticking to it.

Lovely build, the markings are really striking.
