Per the Hogan video title, you are right it's an E / Pitching wedge (http://www.golf.com/tour-and-news/final-duel-sam-snead-vs-ben-hogan-1964), but that automatically mean it's a full shot. Swing speed & body action look close to full, but follow-through looks a bit 3/4 to me. Per Power Golf his PW was his 50-105 yard club and I expect in the 60's his e-wedge loft was considerably stronger than his old set so it likely would have had a deeper range. But I agree it's closer to the max range side than the min range side so it's not a great 50-yard wedge / pitch example. Here is Hogan at a more intermediate wedge distance:
How do you know what club he is using? It looks like that shot could be anywhere from 60 to 100 yards. Camera perspective shrinks relative size of distant objects.
IMO the camera is aimed right down the target line to which his stance is slightly closed (right foot drawn back a bit). The ball and dirt explosion (not the divot itself) at :09 both fly straight toward the center of the bunker that is visible to the right and rear. Can't tell from the pics, but expect the pin position is just left of that line or possibly even right of that line. Ben Hogan is not aiming for the center of the green from that close.
@collapse here is a counterpoint to the in-out path 'feel' on pitches for consideration. For Ridyard, the in-out path raises his smash factor too much over a 1:1 relationship, which hurts his distance control. I suppose it all depends on what works for your mechanics / feels.
