Hi Dave,
Many thanks for the details, I'll see what I can find out during the week.
With regards to the photograph I would think that several copies were made from the original negative and possibly distributed to friends or family, or even a neighbour. I did try to replicate the shot last year and tried to get in the same position as the original photographer. This needed access to a Small lane going up the hill to an old quarry. Big notice, beware of the dog and barking coming from a shed. Mission sadly abandoned, don't like big dogs!
I have been in photography all my life and sometimes have produced over a hundred copies off one picture that have been sent worldwide. I also sorted out our family photo archive when parents and Grandparents died. Many of the photographs were duplicates from different sources. Some photographs of myself and my brother had comments on the reverse made by unknown persons! Never did find out who they were, or why they had copies of the photograph.
Regards
John
