Notes warning the Titanic required more lifeboats were not even presented to the inquiry into the disaster.
The notes were written by Stoke-on-Trent born Captain Maurice Clarke the board of trade safety and emigration official who inspected the Titanic before it set sail.
Leading auctioneers of Titanic memorabilia, Henry Aldridge and Son, will put the notes on sale during their final auction this year. They said they are estimated to fetch £20,000-£30,000.
