From what I've read (the Carpenter and Litwin books et cetera), Shaw was assigned to the SOS in the war not the OSS. The SOS was Service of Supply. He was a supply officer who, among other duties, was assigned to help stockpile supplies for the Normandy Invasion; he was not an intelligence officer. According to his military records he was stationed in England, France and Belgium during the war. He was never in Italy.
Roughly ~24,000 people worked for the OSS during the war. Including the famous chef Julia Child (her maiden name was McWilliams).
Here is a list of those people: https://www.archives.gov/files/iwg/declassified-records/rg-226-oss/personnel-database.pdf
Shaw is not on the list.
And, for kicks, here is Julia Child's file. She was a typist and administrative assistant during her service and was paid $2980 each year (she was not a "spy"): https://catalog.archives.go v/medialive/61/1806/2180661/content/arcmedia/oss/McWilliams_Child_Julia.pdf
Carpenter's research discredits Litwin, so what you took away from reading Carpenter's book were only the points that confirmed your bias.

I found
that confirmed my research was in Carpenter's book.Fred, by including images of Nicholas Lemann's GQ article,

without disclosing that Nicholas Lemann's step-grandmother was the mother-in-law of David Baldwin, who had informed Shaw that he, David was the godfather and first
cousin of Garrison's wife, Leah, indicates Fred buys into the entire charade, and that you do, too. It is obvious
Nicholas and Garrison were misleading both Joan Mellen
and the editor of Garrison's "On the Trail...." Zachary Sklar, who was also Oliver Stone's co-screen play writer of JFK, the movie.

Here is the link to Nicholas Lemann and Zachary Sklar trading letters in GQ, after the Lemann?s Jan., 1992 article was published?..
Lemann responds on pg. 2, to Sklar?s letter which begins on pg 1.:
