A fascinating piece!  The exact wording on the shield in descending order reads   CHURCHES OF CHRIST CRICKET ASSOCIATION  CHALLANGE SHIELD  ESTABLISHED 1931  Definately from South Australia and was purchased with another similar shield at the same time. The shield measures 15.3cms high x 13cms wide, weighs approx 127 grams and is stamped  EPNS A1  in tiny letters to the base. Just needs a good polish and would come up a treat!!
