Simon P. Hanscom

[Rsmyth]

Prior to Booth entering the box Simon P. Hanscom delivered an envelope to the President. The message turned out to be of little importance; it asked for a permit for two former Confederate
officials to visit Washington and have a meeting with Lincoln.
I thought the message was in the National Archives. It is not the papers Edwin Beede picked up since those are apparently lost. Can anyone confirm the whereabouts of the Hanscom papers?
