Bob Starr

Although this photo looks like it might be from AMG, I'm not so sure.  Bob did a film for Zenith with another muscular guy.  The two guys do some exercises in the rain.  The film was promoted in AMG's Physique Pictorial, so it's possible it was produced on the AMG lot.  

This is my second post with a photo of Bob Starr.  Click the label.
