Sure, you are welcome. As McMillan concluded it was probably just the KGB checking Oswald out. Still, odd that Nosenko/Mailer's interviews didn't mention it though.
Dear Steven,
Why in the world would anyone place any significance on something Yuri Nosenko did or did not say, other than to try to figure out who the KGB "moles" in the CIA and the FBI were that he was trying to protect (can you say "Bruce Leonard Solie," "Leonard V. McCoy," "George Kisevalter" and/or [fill in the blank]?).
Speaking of McMillan, it's interesting that her CIA contact in 1956 (in Frankfurt?) was a KGB "mole" by the name of U.S. Army Major Alexsander "Sasha" Sogolow, who just happened to be the boss of Golitsyn's mole "Sasha" (Igor Orlov, aka "Alexander "Sasha" Kopatzky").

PS Sogolow confessed to being a "mole" several years later, but he was "played back" against the KGB and not prosecuted.
