I just got a hold of a December 1935 issue of Outdoor Life and read the whole article which started this thread. Major Charles Askins was the Editor of the Shotguns portion of the Arms & Ammunition section as Col. Townsend Whelen was the Editor of the Rifle and Pistol portion. This article on modifying this 10-gauge DHE-Grade is by J.A. MacKenzie of Toronto. I didn't think that part on the first page about working in Detroit and going home to Toronto sounded right for Askins.
