I guess if Shout says that they now have it, they have it. Also, old information that is no longer accurate may have been deleted to avoid causing confusion.
The information I refer to was the info that most likely alerted Shout to the fact their initial search of the BFI was not thorough enough.
I believe it referred to a UK broadcast of Vault of Horror which clearly stated the uncut version was presented using materials stored by the BFI.
This would have been enough for Shout to look again
