OK, I have the documents in my hands. One is a manual called "Flight Training and Simulator Information" and the other is a "L-188 Study Guide". The latter is a "quick reference home study course for flight crews" and was "built and produced by International Airlines Academy from various manuals and information published on the L-188 aircraft". It's not the Lockheed Operating Manual. It's in a 2 inch binder with some hand notes. The former doc is in a DuoTang folder and is maybe a half inch thick.
If you are still interested, send me a PM with address details. I'll then need to figure out the cost of getting them to you.
