The photo's he provides don't do a very good job of showing the details from an accuracy point of view quite frankly.
From what I can tell:
- The front emitter piece simply cannot be accurate as the it should have a small hole in the front and not an opening big enough for a 3/4" blade. On top of that, the flat front face of the emitter itself was all of 3/4" IIRC. On top of that, there was an inner piece behind the holes at the base of the emitter. Neither of those could be retained with the ability to stick a blade in it.
- The gold buttons are too tall (at least the three rectangles), from the provided photo, the seem too close to the arced button and there seems to be a missing line or two on the aluminum cylinder the buttons are in. Hard to tell with the fine details on those shots though.
-Can't make out the detail on the grip.
-You can't see what it looks like when the grip is attached as there's no side shot.
-can't see the covertech
-can't make out any pattern on the bottom textured grip area.
- at the back end, the pommel is missing a few pieces, the gold ring seems a bit thick and the ends couple pieces seem to have overly square edges.
- I wanna say the grips seem a bit thin, too, but that might just be a rusty memory
That said, i think about half of the inaccuracies are due to making it FX. You simply cannot have an accurate emitter with a blade unless you're making a stunt version. The piece simply isn't big enough. And the missing pieces at the pommel are to make slots for the speaker. Doesn't excuse the height and position of the gold buttons though. Seems as if they could have done those better and then at least provided alternate emitter and end caps for when it's on display as opposed to bladed up.
