This group of hardy men used to keep a watchful eye over Britain’s skies during both wartime and times of peace.
They are all members of the Royal Observer Corps - volunteers who were responsible for spotting enemy airships, zeppelins and other aircraft carrying bombs over the UK’s skies.The group above are pictured in Epworth in the 1950s.
The photograph was sent to us by Mr. William Warwick, 80, who was a member from 1951 to 1955.
He is appealing for anyone who can identify the men in the picture, or the men themselves, to get in touch.
The information will be forwarded for use in the Royal Observer Corps Museum in Alconbury, Cambridgeshire.
Mr Warwick, of Gainsborough, said: “There were about 1000 posts across the country and we used to work in triangles between three posts.
“It was important to communicate to each other if you saw anything to raise the alarm.”
The organisation was formed in 1925 and finished in 1995.
Anyone with information about the picture can contact Mr Warwick on 01427 628151.
