Well, some of Lusitania's surviving boats were sold of (some very cheaply), and at least one or two were displayed until perhaps the 1940's, such as the boat at Broadstairs. The boats from the Mauretania and running mate Aquitania were sold when their fittings were auctioned by Hampton and Sons (1930 and 1950 respectively) and also did not bring remarkable sums.
Hi Eric, I meant the Cunard ships, just commented that the apparent rate of survival for WSL boats was not great.
Hi Ken, It was still considered "scrap", so beyond people who were nostalgic about Olympic no one really would be too interested in spending a large some of money in those days. It was afterall the 1930s and many people were light spenders as a result, and Olympic's furnishings were a little outdated/out of style everything new was "streamlined" to be modern then.
