Danny, your detailed data amazes as always! Everything you say is endorsed by Wikki (unless of course you wrote their entry ;-)
Vultee A-31 Vengeance - Wikipedia, the free encyclopedia
Perhaps more interesting though is this YouTube offering
Some apparently operational footage as well as formation air to air shots showing clearly the typically nose high level flight attitude due to the zero incidence wing (needed for accurate dive bombing). A pity that it is little known now, though at least one still exists in Australia.
Nice of you to celebrate the Douglas Dauntless (a rival to the Vengeance) and a good point that it was what turned the war in the Pacific.
BTW didn't I read somewhere that the Stuka itself was the result of the Luftwaffe buying and evaluating a US Dive Bomber and being so impressed with it that it adopted the Ju87?
