This is actually the real full uncut version.
Now something interesting,
Cut Version (censored British edition) =
94:19 Min.
Uncut Version =
95:50 Min.
There is another copy of this film on the archive that runs 91 minutes which also claims to be uncut. After reviewing the 91 minute version, yes there are small parts taken out, but from what I could tell the cuts were not a result of censorship, but rather artistic choices, and good ones at that. It appears to be a genuine third version of the film and it looks fantastic at 1.1GB in .avi widescreen format, considerably better visual quality then this copy.
I'd recommend checking that version out here

All that said, thanks to the uploader of this full copy, it's valued.
