Orange Monstrosity

This urn with a lid, sitting on a plinth, was bought for my grandmother by a suitor, probably around the 1930s or so.  It is a family heirloom that no one likes but that no-one can bear to part with.

It stands approximately 80cm tall on the plinth to the top of the lid.  It is bright orange (!!) and has a sea motif painted on it.  Distinguishing markings etc covered in the text and photos attached.

Good
