Chugalug,
Ta for the link ! - and a Google <vultee vengeance target tower> brings up a whole lot of interesting stuff: all worth a look. I found <Vultee A-31 / A-35 Vengeance - dive bomber - Aviastar.org> gives a reasonable potted history and the "comments" are the cherry on the cake.
I think your VV is a TT, as the excrescence below the aft fuselage looks like some kind of TT kit (cable paid out and hauled in by an electric motor ?) Always thought the UK ones (Mk.IV) had a pylon on the L side with a windmill as motive power for the cable winch). But here I am hampered by never having even seen a Mk.IV. Even so I have a gut "feel" that your VV is a Mk.I - II (A-31).
sycamore,
...also appears to have visible incidence on the wing..
.
It is extraordinarily difficult to judge the AoI on a VV wing from a photograph , unless you have one of each side by side, taken from the same spot.
Danny.
