Victorian Silver Plated, Mother of Pearl MOP Fruit/Dessert Knives & Forks Pistol Grip Handles

A set of 12 fruit/dessert knives and forks in a wooden, possibly mahogany, case. 

Handles have a pistol grip shape. 

Both knives and forks are decoratively engraved and the ferrules/collars have a shell motif. 

Each piece has a makers mark possibly William Hutton & Sons

In a very reasonable condition for the age, would probably benefit from a clean but am unsure how to do so without the possibility of damaging them. 

The case is in sound condition although here is no key for the lock and the lock is untested. Internally in good clean condition.
