Well i know that you could see it both versions during the Last Great Battle...or whatever they call it. As for Rivendell, i saw the spear to the right of the mural and failed to see Aiglos. No, i think that was just a spear from Rivendell. So then it is Peter Jacksons blunder. The thing i do not understand, is the he had Aiglos, why didn't he use it. Now i think it's because there's a big deal about Narcil and Anduril and reforging and such, so they didn't want to cram the viewer's with one more sacred weapon. Unless it was done in post production and you get tons of problems there. So, I guess they ditched Aiglos. But then, i don't think it would be a big thought to them.
