I came across the August 1980 edition of "Camera" magazine and a feature on three sports photographs of the time, namely Eamonn McCabe, Leo Mason and Don Morley.
McCabe, of the Observer and at that time double winner of Sports Photographer of the Year explains how he worked at events too far away from London for a messenger service. The article took as an example photographing the Grand National where:
"One photographer will cover the first and last fences, while the other will attend to Beechers. McCabe shoots normally, quickly develops the films , in the already erected and prepared tent, knocks off a couple of !0 by 8 inch prints and puts then on a "wire" machine which feeds them to the newspaper HQ in London".
