A notice published in a 1919 trade journal describes the ship:
Shipbuilding in Calcutta. — The S.S. Prosperous built by Messrs. Burn & Company for Mr. S.N. Roy of Chittagong has been successfully launched from Howrah She is 153 ft. long and 24 ft. in depth. There is accommodation for 12 first class and 300 deck passengers and the carrying capacity is about 500 tons. This is the first vessel built in India under rules and takes the highest classification as a seagoing ship. Every part of the vessel has been manufactured from imported raw materials, mostly American. She will run from Calcutta to Colombo and back touching at Akyab on the way.
At the time the S.S. Prosperous was launched, present-day India and surrounding countries were under British colonial rule. Chittagong is the second-largest city in Bangladesh, and was then and now its main port city and a financial center. It was a major center of trade with British Burma and hosted many prominent companies of the British Empire. Howrah, where the ship was built, is a city within the Indian state of West Bengal, across the Hooghly River from Kolkata (then known as Calcutta).
Engraved inscription on silver plate: “S.S. Prosperous, Built by Messrs. Burn Co. Ltd, ‘Howrah’. Sponsored Mrs. H. R. Stark. Owner Sonaton Nityanundo Roy Esq, 24 Oct. 1918.”
Condition: Generally very good with the usual overall wear and handling. A few minor round indented marks on one hammer end where apparently used to hammer something.
