Fem. model Diana in Peter Gowland video by Kodak (late '70's or early '80's)

Way back in the late '70's or early '80's there was a video (available on at least VHS format at the time) by Kodak about how to photograph women, with the late very renowned glamour photographer Peter Gowland, and in it there was one particular stunning model -

So anyone whatsoever possibly recognize her at all or have any clue(s) as to whom she could possibly be? In the video, they said that her name was Diana (or she could be Dianna, Dyana, Dyanna, etc.), but no last name was ever given, so if anyone could come up with anything helpful whatsoever, it would be tremendously appreciated - THANKS very much, as always!
