I just joined this Forum a few days ago, but I notice that many comments reference "The Book of Colt Firearms" By Wilson. I have the original version of that book (with blue jacket)
which lists the authors (note plural) as Sutherland and Wilson. As a trained scientist who has written many peer reviewed technical papers, I know that one should always refer to the
original seminal publication as opposed to later editions unless the later editions contain specific new information not in the original.
I understand that Sutherland has passed away, but I suspect much of the original research in the original edition was done by him. I hope people in this Forum will not let the record
of his accomplishments be lost.
