Shoulder belt plate  © Parks Canada What is it made from: It is made of copper alloy and likely gilded. Where was it found? It was found on the lower deck, on the forward port side of the ship, along with a sword hilt, two uniform buttons, and other artifacts which we know are British Royal Marine and Royal Navy standard equipment. What makes it really special? This shoulder belt plate evidently had been issued to one of the 13 Royal Marines from the Woolwich Division that sailed on the expedition. Thanks to the ship’s muster lists, we even know their names.
