Just one example of many Trench Phones used during WW1 type Telephone Set D Mark III. This one made by Martins Ltd of Birmingham.

Your comments:

• It appears to be a D111** Most likely a "Sterling" 1918 made item
  The real maker and date of the D111** will be on the back of the metal case if the unit is removed.....
  
  Martins Ltd was a leather goods company, they were one supplier of leather cases and and fittings....
