Gary,
This is a really close match, but I'm not 100% certain.

Here was my thinking on Lentz.. The eye and nose area looks the same and he appears to have a tall forehead in both. Initially, I questioned the chin area even though both are similarly rounded, the unit photo image looks thinner than the other. However, consider that he is looking down toward the photographer from an elevated position and that would more than likely cause the face to "bunch up" a bit as the chin got closer to his chest. I also took both photos and sized the heads identically and all of the features matched up and all of this convinced me that this is Lentz. What are the thoughts about this? Take a look at the image and see if there are alternatives that I may have missed before we label the photo.
