Infos about a S 100

[STFenFrance]

Hallo,

I may have the opportunity to get a S100, it's a 1968 model, Henschel 561 engine, 2x4 gearbox, don't know much more about it at the moment..
As I know some S100 and upper are pneumatic suspension, are the spare parts still available ?
Regarding to the S80, is there some particular points to look at on this model ?

Many thanks
