If I recall, Yoda was let in of the secret near the end of the Clone Wars and presented it as new info to Obi-Wan in ROTS, so I would buy that that Vader didn't know about it.
But that's the point: the Jedi didn't know about it either, until Qui-Gon, and that's why Vader didn't know about it.
Scripts are not always the most accurate depictions of the story, given ad libbing, post-production editing, changes of premises in later movies, etc. So that idea, while the intent at the time, may not be the case now.
No later movie came out to establish the premise "Anakin disappeared"; in fact, if they had really wanted to push that idea in the movies, they had ( in theory ) the opportunity to do so when they released the Special Edition... or when they released the DVD... or when they released the Blu-ray. But they declined to do so, for some reason.
"This little scene where he burns his father's body, it wasn't originally in the script." - Lucas, ROTJ DVD commentary, released in 2004
So the intent in 2004 appears to match 1983.
CorporalCaptain said:I can think of an excellent and obvious reason why Luke would put Vader on the pyre with his mask on: To conceal Vader's true identity from all the witnesses who might be watching.
I can think of a better reason: not thinking the kids in the audience needed to see the gruesome sight of the flesh on Anakin's face burning up and melting off, etc.

I am aware of the novels, the Clone Wars, etc. I'm strictly talking about the films, and in the films it feels like the Jedi stumble their way through.
There are supposed to be three years between the movies in question. Three years full of the characters doing things that we don't get to see. We only get allusion in ROTS to the fact that they have been looking for Sidious during that time. "Didn't see it, didn't happen" is generally fallacious and doesn't work in a series with significant time gaps.
