Where is Aeglos?

[Mithalwen]

The elves bury their dead but somewhere it says that their physical bodies disintegrate swiftly - however the Dead Marshes are meant to contain the corpse of the slain from the battle though after so long it must have been some phantasm.

No doubt the elves would have made special arrangements for their leader's body if possible but I don't know if they would have buried him with his weapons - it seems unelvish. I must admit - and this is an impression rather than something I believe I could provide evidence for - that the fact that the ring was "as hot as a glede" when Isildur took it, suggested to me that Aeglos (and possibly also Gil-galad was more or less incinerated in the process of killing Sauron. Of course Narsil was merely broken but swords have special qualities in Middle Earth and are not usually largely constructed of wood. Also a spear would probably have been embedded in Sauron whereas a sword can be more of a slashing weapon.

It is a theory, but I wouldn't bet the farm.
