There seems to have been a seventeen year gap between issues 3 and 4 of WANHS newsletters! Newsletter Number 3 (edited by Bill Copley Jones) is dated October 1992. There were no more until Jenny Kingsbury took on the role of editor/production manager in 2009 and produced editions in both September and December of that year.
Prior to Number 3 Bill produced Number 2 (which, although not dated, seems (from the content) to be Spring 1991).
There is another which is entitled 'Centenary Newsletter Spring 1991' so it would seem that two were published in quick succession.
A previous newsletter (presumably Number 1, since numbers 2 and 3 are accounted for above) declares itself to be an 'Autumn Edition'. From the content it would appear to be Autumn 1990, although a handwritten '1989' appears on the front page.
