The Parker Bros. I have noted Chas. Askins the elder writing about was his 6 3/4 pound 30-inch 28-gauge. In his 1910 book he writes of hand loading 2 1/8-drams of bulk smokeless powder and 3/4-ounce of shot in the 2 7/8-inch cases when the heaviest factory loads offered were 2-drams pushing 5/8-ounce of shot.
In the late 1920s he got a fully loaded No. 5E NID 16-gauge, but it ended up spending much of its life with Elmer in Salmon, Idaho.
