do you guys think the tape on the graflex clamp is only to cover the graflex logo in the ranch? i mean come RoTJ they didnt care about coving the graflex logos on the v2 and v3. its only until lucas film decided to display this in public where we see the tape covering things up
There is an easy explanation for that....
If the "Ranch" GRAFLEX was actually PLANNED to be the "NEW ROTJ SKYWALKER SABER!!" they would have had the time to try to clean it up from how it may have been left post "Empire", apply new textured tape to the clamp, etc.
In contrast, the V2 was most likely grabbed out of the "box o' lightsabers" in a panicked "we screwed up! Get us another lightsaber" atmosphere on day one of filming. At best, they had time to grab the V2 out of the box, remove the blade, and attach it Luke's belt. They simply did not have the time to clean up the chipped black paint, scrapes, dents, and naked clamp, on the V2 (thank God

) I am sure Lucas said something to the effect of "we can fix this in post production by inserting shots of a truly brand-new saber that looks like this one....no one will notice the difference...", thus, the creation of the V1, "insert shot" ROTJ hero hilt after the fact...
It's really kind of funny that we may have gotten the V2 as the basis for the "Skywalker ROTJ Lightsaber" as the result of bad planning and a failure to mind details in the prop and design department. Otherwise, Luke would most likely have shown up for "ROTJ" with an entirely NEW saber design looking very much like the prequel sabers.
