Silver napkin ring commemorating the maiden voyage of RMS 'Port Kingston'.

The band has chased floral borders and a coloured enamel house flag in red, white and gold, of the Imperial Direct Line.'Souvenir of Maiden Voyage of Imperial Direct West India Mail Service RMS "Port Kingston" 1904' is inscribed around the band.

In 1901 the Imperial Direct West India Mail Service Company was formed to run passenger and banana services from the UK to Jamaica. The company closed in 1911 and their ships were sold or returned to Elder Dempster & Co.

RMS 'Port Kingston' (7,585 tons) was built in 1904 for Imperial Direct West India Mail Co., and operated in the West Indies as a passenger/cargo ship. In 1911 she was bought by the Union Steamship Co of New Zealand, refitted as passenger only and renamed 'Tahiti. She operated on the Sydney-Wellington-Raratonga-Tahiti-San Francisco route and also served as a troopship in and immediately after World War I. She was involved in a shipping accident in Sydney Harbour on 3 November 1927, when she collided with the ferry 'Greycliffe', which sank with the loss of 40 lives, including many schoolchildren. In 1930 RMS 'Tahiti' herself sank south of Raratonga after her starboard propeller shaft snapped and holed the hull, but all passengers and crew were saved.
