Original block of wood removed from the shed built by Harland and Wolff to test Titanic’s engines. Heavily oil and paint stained block measures 2.75 x 3 x 2 and has two grooves cut into the bottom for a batten to be placed to hold them together. During the testing phase the engines had to be operated at full speed. To keep the resulting vibrations from destroying the facility, Harland and Wolff lined the floor with wooden blocks that could vibrate individually and lessen the strain placed on the building. A small plaque is affixed to one side of the block. Accompanied by a certificate of authenticity from Harland & Wolff as well as its original box.
