Old Silver on Black

Whilst ferreting around in the understairs cupboard I found a bag full of my grandmother and mother's old cutlery.  I'd thought it was in the loft.  
As I'm not really going to use it I might as well clean it up and see if it is worth getting rid of to someone who might use it.  These unusual spoons were amongst the 'haul'. Thought they'd fit today's challenge....
