John C. Wright's handwritten memoir were supposed to be in the Camden Library where a noted south Arkansas historian hand copied them and privately published them in the 1960's (without copywrite permission) along with 4 other books in Pine Bluff. I believe that someone (maybe Mr. Justice) obtained a copy of those papers for the purpose of republishing them but because of the previous publication ran into trouble of getting the copywrite permissions.
There may be a copy of the 1960's publication in the Pine Bluff Library possibly in the rare books collection. At least there was the last time I was in that Library. However that Library has sold many of their collections in past years. Such as an original set of the O.R.'s.
