We'll probably never know.
The Hi-E hub may have been the inspiration for the WTB greaseguard hubs. Charlie may have experimented by adding grease ports to Hi-E hubs, but I don't remember ever seeing one. I worked as an apprentice for Charlie in 1983 after that, I opened the closest bicycle store to his house/shop. I have spent a lot of time over the years in his shop with him showing me his latest projects. In my opinion, the author of the article is not correct. Greaseguard happened with the WTB hubs that I think were machined by Paragon.
