For all intentional purposes, that is the A New Hope hilt.. at least for the Legacy line. Only a fraction of a percent would notice that difference between a modified Revenge of the Sith version and the A New Hope version. And even a smaller fraction care.
...and TheRPF -IS- that fraction.
Which is why these highly detailed, ALMOST screen replicas can never be perfect for us. But I am still VERY happy that these "close enough" high end pieces are even being manufactured at all! Without that Uber fandom fraction for Star Wars, these high end replicas, fiberglass helmets, Disney+ TV shows, heck even Galaxy's Edge would probably NOT exist.
