"Achtung Spezial-Ol Sperrdifferential" is a tag that denotes this diff is a LSD and requires special gear oil.

Now looking inside of the diff.
Picture of a 2.47 open carrier from a 1986 w126. Notice the curved carrier. No clutch disks can fit in there.

Early 2.47 LSD carrier, picture of a 1987. Notice the "squared" carrier and the clutch disks at the spider gear.

Later 2.47 LSD carrier, pictures of a 1990. Notice carrier now covering the clutch disks. But does not have the shape of an "open" carrier. I think the additional material was added for strength.
