The lightsaber you mention is actually 3 different sabers, each with its own unique features:
- Anakin Episode III (has gold highlights)
- Luke Episode IV (has a bubble strip on the activator)
- Luke Episode V (has a circuit board connector on the activator)
I'm pretty sure Master Replicas made each of these. So I would suggest you do some research and see which one you like.
I myself prefer Luke's Episode IV saber. I have the Icons version. It's a reasonable replica, but if you want it to be as accurate as possible, you need to build one yourself using a real Graflex flash gun.
