The first definitive article on the gun was by Dick Baldwin in a 1969 Guns and Ammo magazine. Oddly, Guns and Ammo publisher Robert Petersen became the ultimate owner of the gun years later. The full story was published recently, co-authored by those who know the facts. I cannot relate the complete bibliography on the gun, but someone may be able to lead us to the latest article which, I think, was authored by Dietrich Apel and printed in the Parker Pages.
