This oil stained anti-vibration wood block was removed from the shed built to test Titanic's engines. During the testing phase the engines were operated at full speed. To keep the vibrations from tearing down the testing facility, Harland & Wolff lined the floor with wooden blocks that could vibrate independently, lessening the strain placed on the building. During shipment it was packed with a vial of rust powder from a salvaged piece of the Titanic. Some of the rust spilled out and ironically coated this wood block.
