Another cork block, also saved by Mr. Ogden, used to be in the possession of an anonymous collector.
The collector was an ophthalmologist, and Mrs. Ogden was one of his patients. They became close friends. One day she presented him with a valuable gift  – a cork block that originally had been part of a Titanic lifebelt. The doctor was delighted to have such a relic and had it framed in a shadowbox.
For many years it hung in the forward cabin of their yacht. There it stayed until one night in August of 1995 when the yacht, moored in a boat-yard, caught fire. The boat was completely destroyed. Despite that fact, local firefighters drenched her with water so that she sank to the bottom of the dock. Mrs. Ogden’s cork block, in its glass case, sank with it yet somehow had survived the preceding inferno. Ironically, for the second time, the piece of cork had been cast upon the water and reclaimed to again become a precious keepsake ashore. [1]
