Naval Long Service and Good Conduct Medal (1830) with the effigy of Queen Victoria on the obverse, the image of a three-masted man-of-war on the reverse and a new Navy blue ribbon with white edges. Naval Long Service and Good Conduct Medal (1830) The Naval Long Service and Good Conduct Medal (1830) of the United Kingdom was introduced in 1830 and ratified by King William IV in 1831. It could only be awarded to selected Navy ratings after altogether 21 years of service and good conduct. The medal remained in use until 1847, when it was replaced by the Naval Long Service and Good Conduct Medal (1848). The
George Cross ribbon width was amended to one and a half inches. Bars can be awarded for further acts of bravery meriting the GC, although none have yet been awarded. In common with the Victoria Cross, in undress uniform or on occasions when the medal ribbon alone is worn, a miniature replica of the cross is affixed to the centre of the ribbon, a distinction peculiar to these two premier awards for bravery. In the event of a second award, a second replica would be worn on the ribbon. Recipients are entitled to the postnominal letters GC. All original individual GC awards
