I wasn't ( necessarily) referring to the pictures, but to the actual positions had by gun holding through time, specialy when accurate aiming appeared.
The different stock holding stages: chest, cheek, over shoulder and shoulder front, together with their respective stock designs, must have followed an ergonomic evolution, joining conveniences like sustaining the firing impact and a permanent improving aiming intention.
... if i make myself understood.
