I don't have any top-down pics of it but I know what you are talking about. Some of their jigging (especially "deep canyon") requires "fat" bone, similar to some stag. Some people like that, some don't.
The Winterbottom jigging is well done. It's more like a broader version of the barnboard. Doesn't add to the thickness of the bone, and is comparable to Amber Bone or one of the other typical jigged bones. It adds some grippiness, but only perpendicular to the grooves. Not that big a deal in a pocket knife, and certainly more than a smooth bone.
I think that run was from 2012. The reason I ended up with two of them is that the last ones were selling out when I was shopping for them in early 2013 and I ordered from two different vendors at the same time. I think I got the last one in stock from both of them.
Case later came out with a Red Brick Winterbottom Bone in the same pattern in their Select series, which looks a lot like my dyed version but with a bit more red to it.
I used a combo of Cocoa Brown and Scarlet RIT dye, 2:1 in favor of the Cocoa. The dark lines in the valleys are from a black Sharpie marker right after dyeing (the bone absorbs it, it's permanent).
