Thanks for the lead darkith. I was really amazed that none of my ref material covered gun traverse limits. I was in a Stu III a few years ago in Germany and it seemed to me that traverse was a bit restricted on the right....maybe the vehicle was damaged. With all the interest in the Sturmgeschütz, I'm going to have to convert one myself. It's a wonder HL or someone hasn't come up with them. Century 21 has the Brumbär, but it's the ridiculous 1;32 scale.
