Awhile back I put a couple of Opel Solex manuals on cd. Several people have made inquiries asking if I had more copies. I have more and can make more. One manual is the Opel Solex Carburetion and Tune Up Training manual (1.1 and 1.9 carbs, October 1970 about 62 pages) and the other is the SPA Opel Solex Step-By-Step Servicing Manual (covers the 1.9 carbs up thru 72, about 23 pages).

The going price seems to be $5. This covers materials, time, and shipping to your door.
