Correct about P-40's, also P-39's. P-40 was able to outturn 109 below 10.000 ft & I admit having a fair amount of admiration for this plane. Tough it was. Bueligen & Rall didn't think much of the 38, but Macky Steihoff certainly did. It had teething probs early on which it overcame in J & L models. My neighbor flew early & late versions, said it was real hard to roll the early ones. He also said he dove a P-40 & had to stand all his weight on the left rudder to keep it straight.

Dunno if it was used in any serious numbers in Op torch, 38 I mean.
