Harry Hayes was a knowledgeable SA philatelist and was also the first editor of the SA Philatelic Circle Journal (1991 – 2005), later called the Australian and again later the International SA Philatelic & Historical Journal. His home corps was Batley Castle. In 1978 they tried to build up a building fund. To support the fund, Harry issued a few limited FDC issues of the 25th Anniversary of the Coronation of QE. A special “parachute post” slogan PM was added and the text “Issued in aid of the SA Batley Castley Building Fund”. The shown cover here was made in a very limited edition of 45 and had two prestamped QE 5p in addition to a single blue coronation stamp.
