Yeah 4050 was withdrawn after accident damage (brake failure on Service X66 I think).
4050 had to be the worst Prestige I had the misfortune in rifding, it rattled like hell, it sounded awful and one day it was making an alarming noise that sounded like someone was playing Operation next to me. Hated that Prestige glad its no longer with us.
