Here’s a trio of the best original condition 280SE owners manuals you can find. Includes the parts book and the service stations. You can see how crisp the pages are and how they lie.
The owners manual is so clean that the first page is not fully cut at the end. See the last pic.

If you don’t need all 3 I may consider splitting them up.

I also have other pieces to the manual packet like the Kangol seatbelt leaflet, the Becker radio manuals, odometer paper, etc.
