Cant help you with the markings since I'm not that good on older campy but do you really care if the locking is original or not if it fits? Thats going to depend on your hub anyway. Some older freehubs take the 26mm lockring but some will need the 29mm (which i think is the 8speed original). Current size is 27mm.
