Weird, it's not showing the photo in the post for me. Anyways, the one WITH the center knurling was the one that confused me. The knurling comes in WAY more than a bar typically does and the ring markings are also brought in more. It's the most baffling shit I've ever seen. It's like someone was just designing a bar having looked at one once. "Yeah, it has those ring markings on it, gotta put those...somewhere".
