The contents of any particular pouch, however, may cover any period starting after 1913 and ending up to c2002. When seamen were discharged some or all of their documents (including the index cards) were placed in the pouches and these include discharges of seamen who were originally registered in the Central Index Register of 1913 to 1941.
