Historical information
The SS Diomed was the last ? of the Blue Funnel Line's coal burners and the 4th (of 5 vessels) bearing the name Diomed and built in 1922. She made her last voyage from Australia to England in 1952, where she was broken up. The ship had been in service in Australia for 30 years and as a parting gesture the ship's bell was presented to the Mission by Alfred Holt & Co., the ship's owner. The bell was originally presented to the Port Melbourne Mission to Seafarers. It seems to have been a mark of respect for one of the Mission workers who regularly visited the ship. On closure of the Port Melbourne Mission in the late 20thC , the bell was transferred to the Melbourne facility and has been in permanent residence since then.
Rgds.
Dave
