Hben try this video of Hogan:
YouTube - Ben Hogan Golf Swing
It really shows the position of his right elbow and really everthing Hogan teaches in his book. Hogan talks extensively about keeping both arms connected to the body with the elbows pointing at their respected hip pocket. You will notice Hogan's right elbow is pretty much glued to his side pointing down to his hip pocket all through the backswing and most of ther downswing until after inpact. Also note his left elbow after impact, a mirror image of the right down next to him. It is a easy and repeatable swing to master with practice.
There a dozens of video on you tube. Just Google "HOGAN SWING VIDEO" for thousands of hits.
