I've moved things around a bit on PictureTrail. Here's the Davenport 8g Elite Heavy Target ad from the 1904 Supplee Hdw. Co. catalog. Now "Armour" steel; used by Meriden Fire Arms and Crescent for decarbonized steel. Hunter Arms "Armour"/later "Armor" was comparable to 1211 rephosphorized and resulfurized low alloy steel as well as 1045 "plain carbon steel".
