The Mayor, Steve Parish, and his staff who are unstinting in their access to the Town's Archives and assisting in everything related to the ships named "Ajax". In particular their generous hosting of my and my Wife's visit to the town along with fellow members of The Ajax & River Plate Veterans Association in June 2014 to celebrate the 75th Anniversary of the Battle of the River Plate. Also for the dedication ceremony at that time of "Sharplin Drive" to the memory of my Father, Robert John Sharplin, in the presence of my Wife and myself and other Association Members, a truly moving experience.
