Looks like the same pack, only mine is only half the age of yours. They made mine with a detachable daypack that attaches where your front pocket is. Also they made the daypack/pocket smaller -- so I doubt now that one could get 11x14 holders in it. Mine is also a nice middle gray -- I should meter it and a gray card and see how close they are.
My Zone VI 810 fits it with lots of room -- so I was able to use closed cell foam to pad all around the camera. I put it through baggage for a trip from here to New Mexico (3 different planes each way) and it did very well. It is nice the way it refrains from yelling "There's lots of expensive camera gear in here!" I removed the daypack and carried it with the holders/film as carry-on.
The nicely padded leather handle on the side is great for moving the pack around. My pack also has two side pockets that hide away when not needed -- long enough each for 2 1-qt water bottles. I could not tell if yours has them. For all-day hikes, I take a water bottle and my water filter in one side pocket and food in the other.
Do you actually pack it with the GG facing the way you have it in the photo? I added good padding beneath the camera -- with that padding and the padding of the shoulder straps and lower back, I feel my GG is safer the other way round. The padding I put beneath the camera (that the GG goes against) is two layers of closed cell foam (backpacking sleeping pads) with some stiff material inbetween -- sort of like 8-ply rag matboard, only made with some cheap cardboardy sort of paper. The stiff material is to keep a rock or something from putting too much uneven pressure on the GG if I set it down too hard.
I also used some open cell foam at the end so that I do not have to worry about setting the pack down hard (after 10 or so miles, and 8 or more hours of photographing, it can be difficult to gently ease the pack off my back and onto the ground!) I think I have to replace this foam as I heard more of a clunk the last few times I set the pack down.
I'll have to measure my pack...I have just assumed a 15'x15" camera (outside dimensions of an 11x14 w/ reversible back?) would not fit in mine --perhaps due to the extra padding I have on the sides.
