The Whole Duty of Man

I am seeking a particular copy of the 18th century book called ‘The Whole Duty of Man’. It used to be chained to the lectern in Fairford parish church in Gloucestershire. It was definitely there in 1939. It is thought to have been there in the 1970s but that is not absolutely definite. It was not there in 1984 when a survey was taken of the church archives. Does anyone know what happened to it? It is only this copy that I am interested in.
