Lands end

This is a massive anchor. From the age of barques and schooners. Many of them had the name of the port of build cast into the shank. This is precisely what I mean about pointless displays (as nice as they are and as much as it is better than rotting away on the sea-bed) it does nothing to let people know just what it meant to be at sea and what was necessary to keep it from being grabbed by the sea and thrown against the rocks. This anchor had to be manhandled.

Looks like an Admiralty Longshanks pattern anchor of around 1840 or earlier, but there are aspects of the design which may point to it being French.
