Neil & Jim & MHW -
Photo G is definitely not the current (post WWII) #11 green at Dornoch, as there is no green between the current #11 green and the water, as shown in the pre-WWII photo. I do think the current 11th hole was one of the holes added to the course after WWII, along with current holes #7, #8, #9 & #10.
My first guess (above) was Photo G was the current 17th green, with the current #14 green (Foxy) in the background. It could also possibly be the 3rd green, with the current #13 green in the background.
I do not know which and how the surviving holes were re-numbered when the new holes were added after WWII.
