The order of precedence for the wearing of medals was set out in the RIC Code (Regulations and Standing Orders) and by official circulars issued by the RIC Office.
In earlier years, the Visit to Ireland medals, as awards from the Sovereign, were given precedence over any other medals including Gallantry and War Service medals. Thisd is evidenced in the following circulars and extract from the Code, dated 1904 and 1911 respectively.

The RIC Code 1911
Note also the instructions on when medals were to be, or not to be, worn on full dress or patrol tunics. In 1917 the regulations were slightly amended and for the first time we see evidence of the use of medal or ribbon 'bars' which were to be supplied by retailers in Dublin.
