The picture caption also says that a grease guard port has been added, although this may have been an erroneous interpretation. It's interesting to try to figure out how a grease guard system could have been added, given that it needs internal seals to direct grease only to the bearings and prevent the grease from filling the whole hub cavity in order to work as Charlie intended.
Well I can't say for sure that this particular hub was GreaseGuard™, but the early GG hubs were in fact Hi-E hubs that Charlie deconstructed and modified. How the internal seal worked, I haven't a clue. But this hub could be one of those, and I'm gonna say it likely is, since the person who took the pic and wrote it up says it is. We'll probably never know.
