Now this is research and thinking without the dictatorship of Mods. The LAP has always looked like the product of a HP Engineering Plotter produced on roll vellum plotter paper to me. Elevenaugust, your findings are always relevant here and to me.

Lev: Didn't Isaac clearly state that it took many people months to make the LAP documents? This proves it had to be done old-school using an Engineering Plotter on vellum.
If it was made last year it could be done in days using computer CAMCAD software and by one person.

Douglas, you're quite right...
The LAP surely was made by a Xerox Plotter (PACL was a part of Xerox):
