To anyone who's interested:
Idly roaming around on Key Publishing Co., came across this Link put in by "jagan" (who is well knowh to us from BHARAT RAKSHAK):

This is a string of YouTubes, the first showing the IAF and their VVs (I loved the shot of the little capuchin monkey vainly trying to get up the u/c leg to get up on the wing [pilots used the same way - right foot on wheel, left in the "stirrup", quick scramble, and you're on top], and later (the monkey, that is) gambolling all over the aircraft.
Third youtube is a history of the Vultee aircraft by Pat Macha (?): there's only a bit about the VVs from 25.00 to 27.20 (out of a whole hour !), but plenty about the BT-13, but let's just say that opinions vary about
that aircraft !
Of course, the best bit of video about the VV is still the well known "Vlad" compendium of shots.
