The pictures of the "9th" green in '34 and '39 are so different because they are different greens.
Remember, the course in '34 played opposite what it has since.
So, the picture of the 9th green in '34 was actually the 18th green in '39, and visa-versa, of course.
Notice in the '34 picture the bunker corner peaking out of the front left of the green. That is the bunker left of the current 18th green. That photo must have been taken from 30 yards right of the current 18th green and the current 9th green is behind and a little left of the gallery, slightly down the hill, hidden.
In the '39 picture, look at the bunkers left of the green and compare them to the bunkers in the modern picture of the 9th green. They are positioned almost identically.
