Meritorious Service Medal
Until November 1902 holders were not allowed to wear the Long Service and Good Conduct Medal (LSGC) as well as the MSM, but thereafter both medals could be worn, the LSGC taking precedence. In 1979, however, the order of precedence was reversed. From 1956 recipients needed at least 27 years' service to become eligible, but this was reduced to 20 years in 2002.
