Hey guys, I have seen the movie closely and have noticed that the Obi wan AOTC lightsaber in the movie is the same one as TPM lightsaber. I realize that master replicas made the AOTC one out of chrome and TPM one out of alluminum but I stand corrected when I say that they made a distiction solely for marketing purposes. The same is said about the differences between AOTC Dooku and ROTS tyranus. I have seen the movie closely and the "screen accurate" version is the tyranus. In both films that he's in, the saber does not have a gray part at the hilt, it's all chrome. I will post pictures to confirm it.
