I have two original owners manuals. The first is moderately tough with the usual wear of having been lying around and tossed about . It also has directions to a dealer scrawled inside the cover page. Might be an English address.
The second I got from an old Lotus employee who picked it up from spares. It's immaculate except for some small edge damage do to being moved about in storage. He knew what he had, and I wanted it. £500, ouch. Fortunately the pound was low then. This is the one I made the copies from. The copies are identical in every respect except there is a slight moire pattern to the inside photo.
The Service de Carnet I bought off French ebay. I don't speak French so I didn't ask questions. Knowing that the French list made re-pops, it's too immaculate and must be one of those. My re-re-pops are identical in every way. The French lister sold the S1 Service de Carnet with a S2 owner's manual for 50 euro. I sell them for $10US each, a slight loss as it's just a service to the list.
