This image is one of four Profile Publications I purchased in my teens, and still have. Containing only 15 pages, but packed with detailed information: The aircraft’s history, development, variants, color profile pictures showing unit markings, theater of war/ the year(s) used, camouflage, specifications, and weaponry; along with many original black and white photos of the aircraft.
I have never found this aircraft documented, or acknowledged in any WW II accounts apart from the Eastern front.
Attempts to provide any documentary footage from YouTube was a futile effort; the examples were either short German propaganda films, or a plethora of FKG “War Thunder” videos (gamers) no History Channel or other legitimate sources. Relevant information on this aircraft found on Wikipedia: http://www.thefullwiki.org/Henschel_Hs_129
I reluctantly post this one example of the HS 129 from a model aircraft site, with the 37mm cannon in the under fuselage necelle; imagine the version with the 75mm artillery piece!:
