That drawing is dated 6 weeks after the real Vengeance prototype first flew on 30 March 1941.

So it must have been for a variant design.

Also it was mentioned in a book about Vultee.

it's really interesting : 1. twin tail version exist only on project mentioned in patent. 2. Also France before capitulation ordered 300 aircraft.

Given the French Ministère de l'Air's obsession with twin-tailed aircraft, it's indeed safe to assume that the original twin-tailed design was made to order for the French Air Force...

I'm sorry, I'd never heard of such.
Was there some 'internal logic' to this, or was it simply whim ??

From Douglas Havoc and Boston - The DB-7/A-20 Series by Scott Thompson, Crowood 2004, p. 33:
"Another experiment was conducted with aircraft 131, this being the test installation of a twin-tail on the DB-7 design. The French Air Ministry thought that both the design's stability and the aft gunner's field of fire could be improved by the twin tail. Initial testing revealed no improvements in either area, but by the time the tests were concluded, France had fallen and the aircraft was delivered to Britain instead."

The rear gunner's position had a wider area of sight on twin tailfins aircraft, l'Armée de l'Air was beginning to install 20-mm cannons on flexible mounts on its more modern bombers when the German attack occurred.

The rear gunner's position had a wider area of sight on twin tailfins aircraft, l'Armée de l'Air was beginning to install 20-mm cannons on flexible mounts on its more modern bombers when the German attack occurred.

The experiment showed that the 20 mm gun, despite a devastating effect in case of reaching the target, presented an ultimately illusory defense against the attack of single-engine fighter jets by its uneasy handling ... It would indeed have been better to have 2 x. 50, with projectiles certainly less lethal on paper but at a higher rate and much more manageable in terms of shooting and especially loading, and therefore more efficient (we will not talk about 7.5 mm guns as effective as lead rifles ...).
Typical example of this impressive installation if not really effective, the heavy fighter SE.100 ... which one does not know if that concept would have been effective !
