"PRIMARY Source Documents"? These missives do contain dates specifying when they were conveyed. 17+ years after the assassination DQ's "Primary" being applied to them. The dates of these "documents" is far closer to the release of "The Men Who Killed Kennedy" (1988), than the JFK Assassination itself. Context being applied to all things is Crucial. Slow your roll and give this "pen pal" correspondence some serious thought.
