Larry Engesath worked on AQM-34's early in his USAF career. He photographed an AQM-34M with its typical the upturned radome at Beale AFB (CA) Open House, sometime between 1975 and 1979.
Larry also photographed an AQM-34V (Model 255) at Beale AFB (CA) Open House, probably on the same Hercules.
In 2016 a slide was auctioned on Ebay that very likely shows the above Firebees on the pylons of DC-130 '496'.
Concluding, a variety of photos that Larry shot during 1973.
