Antique Monogrammed Leather Gladstone Bag & Sharks Pin Dated 1890 G.D.D.Davies

This is a well travelled antique gladstone bag dating to the Victorian era. The bag is made of brown leather and has a brass name label to the front engraved with the name J.D.D.Davies. Inside the bag, near the top, is a stamped makers label for Finnigan of Manchester. When I was looking through the inside of the bag I came across a strange item that looked like a bone or a tooth, this unusual piece has the bag owners name carved into it with the date 1890 and 'Shark Pin', an interesting momento from a Pacific ocean voyage perhaps!
