Incidentally, I was comparing my new 7C/PP hilt with the original Master Replicas version...which now looks SUPER inaccurate compared to when it was released in 2002! The diameter and overall proportions are very similar, but the MR is of course longer (but still shorter than both the MR and Anakin Starkiller V2 hilts), and most of that seems to be in the grenade section, because the other parts are pretty much proportionally identical. The MR also had idealized/consistent rings.
