Pre WW-II, the "Whiteline" Recoil Pad was made by Fray-Mershon of Los Angles, California. It came in a field style with horizontal lines on the face and a Skeet style with vertical lines. They are still shown in the 1948 Stoegers. By the 1950 Stoegers they are the Pachmayr Field or Skeet Model and there is also a Trap Model
