To my knowledge I do not do as you suggest.
My library is like most others; it is contains some tidbits of information and documents the source of which is unknown and/or unverifiable. The MacMillan letter is one of these documents.
I presented the MacMillan document on my blog for its face value and left readers to make of it what they will. If you have information that lets readers verify the source of this document I will happily provide that information along with the letter scan.
Sincerely,
Marvin Shilmer
