No, these are a separate set of documents and artifacts that were donated to NASM in 1973. As near as I can tell, Harry went through his files at that point and donated what he thought he would not need again. He appears to have retained some critical formative documents, such as his correspondence with Orville Carlisle. He also appears to have retained the manuscripts from his fiction and non-fiction writing.

There are 13 (or perhaps 14?) archival boxes at NASM, consisting primarily of correspondence. Harry seems to have been pretty conscientious about making a carbon copy of everything he typed.
