The ADRIC roll has no regiment, and he does not seem to be on RIC roll. Not enough information to establish who he was. It is certainly "A.C" and "C A " on another but no MIC exists . Numeric register has him as AG
1920 Sep 3. Joined ADRIC with service no. 469 . Posted to E Coy. No indication on Roll of him resigning. . There is a letter "I" on his roll entry, which I did not know what it means. Then I worked out that it referred to AG Imlay who is the correct man for this service no. AG Finlay does not exist
