In 1907 Colin SEALE "Purchased discharge under article 1142 R.W." 26/7/05-13/2/07 1 yr 203 days. 19th Bty RFA
R.W.=Royal Warrant. Since the enlisted man signed up for a minimum term, if he wanted out, he would have sought formal permission and paid a sum calculated on what training he received and the length of service still outstanding to serve. I am assuming that he would also lose any entitlement to a pension.
