The drawing is quite hard to read in some aspects. But internet search for co-occurrences of names that are easily to read led to one article from 1990. This single article “The Banker, the Guns, and the CIA” from the Baltimore Magazin as of August 1990 contains all actors in the drawing but two. We might assume that Lombardi used this article in his research. The two remaining nodes “Zurich Handelskredit” and “Geneva Disc Bk” are mentioned along with their financial relation to “Bk Cantrade” in the Washington Post article “How CIA Moved Some Arms-Deal Money” of Dec. 9, 1986. So far, there was no other drawing whose (nearly) complete information was contained in a single document.
