Help to confirm piece

[Ga6704]

Hello, I dont know if i posted this in the right sort of topic, but i came across this piece wich looks like a 820, but it is red and some people say that it is super rare and others says that it is from set 1235 but it dosent seem to be in red even though it seems like it. I just need help to like confirm what kind of piece this is.

Hello and welcome to EB!

Bricklink says it was made in light gray, red, and white: https://www.bricklink.com/v2/catalog/catalogitem.page?P=820#T=C

but as far as I browsed, no red available for sale - seems really to be rare!
