I would venture to say the grouse covers in Bill Foster's day were much the same as today with consideration to where a fellow chooses to hunt. In many covers open shots are the norm and in others shooting through the foliage is the norm. I'm lucky enough to have it both ways where I hunt in Vt.
Living here in Andover and being quite familiar with the places Bill and his cronies hunted I'm pretty sure he could pick his shots when he needed to. In other words, don't risk the shot if it looks impossible or if you'll only maim the bird.
I'm going to guess the last etching is of a grouse taken at about 45 yards with the left barrel of his Cyl/Full Parker twenty and judging by the devastation of the bird, there wasn't much left for the cook to work with.....
