Hello Mr B.
This is a very nice picture but I am not sure about it’s authenticity, certainly for the 1960’s.
This aerial view was taken in 1967 by Jac Weller for his Wellington at Waterloo book.
The landscape is very much as it is today, even allowing for the time of year.
The electric railway line is clearly visible to the left.
The building seems to have the plaques including the diamond shaped KGL memorial, replaced in 1847.
I wondered if this was possibly a postcard picture that was coloured in of the sort popular at the turn of the Century?
However, this picture taken at the turn of the century showing the extension of the line, to transport crowds to the fallen eagle monument in June 1904, does also provide evidence of recent tree planting.
Perhaps it’s a mid 20th Century picture?
Fascinating stuff.
Best wishes,
Chris
