I think it's probably HG. Fo-o-o! I looked it up from a state of ignorance after receiving it, so I might be wrong. Those who are looking at this probably know more, so maybe they'll understand when they see it. It's not RG! I can say that much for sure! I washed it. I polished the back. An hour and a half!!! I think I got rid of most of the dirt. Pictures 6-11 are either the right or left, and 12-17 are the other one. That's what I wanted to say, but they got mixed up while I was switching the photos. It's not dangerous to mix them up, so I figured it's fine. Anyway, I don't know anymore. There's no way to fix it. If you know the condition, it doesn't matter if it's right or left! Basically, the problems are scratches and dirt on the back, scuffing on the part where the heel hits inside, and peeling of the print inside, that's about it. Fo-o-o! If you're interested, please consider it.
