Yep, VZ was it.

I worked in Life Support (yep, in the air conditioned squadron building where we kept the parachutes, helmets and so on) with the 615th, 1/70- 1/71, and ended up with some 8x10 glossies and other ramp pictures, including VZ 117 (Ltc Aaronson's bird), VZ 937, VZ 365 and VZ 593. Also got a couple of nose art pictures at the 615th, one is "Jody" and the other is "My Pumpkin" with a large orange pumpkin, but I can't lay my hands on that photo at the moment.  Also have an 7th Air Force news clipping showing an F-100, headline reads, "Phan Rang Flyers Kill 50 Enemy."
