Inevitably by looking at Wikipedia we find that;
HMS Rosario relieved HMS Rattler on the China Station in June 1900, and re-commissioned at Hong Kong on 5 November 1913, becoming a depot ship for submarines. In her role as a submarine depot ship, she supported a flotilla of three C-class submarines, C36, C37 and C38. These three submarines were built by Vickers, Barrow, commissioned on 1 February 1910 and sailed with HMS Rosario to Hong Kong in February 1911. They were all sold in Hong Kong on 25 June 1919. HMS Rosario was sold for scrap in Hong Kong on 11 December 1921.
HMS Titania and HMS Ambrose manned the China Station from 1920 on.
That makes my original image on thick card over 100 years old.
