If you are used to a modern shape of an anchor, particularly one for a large ship, the old style of anchors in the days of the early 1800s will be rather strange looking. They look like a giant version of the sort of anchor you would see on a small boat. This example sits on the seafront in Southsea and comes from a ship that fought in the battle of Trafalgar. It seems in pretty good shape. I wonder whether that is a feature of the materials used or the result of lots of bits of it being replaced over the years.
