This medal is OK, correctly engraved, no doubt at all. Medal type with crowned Z only, without F.G. start to be used during WWI; in my collection I've few dated 1917 and a couple 1918. No one dated before 1917 and no one awarded after WWI. This do not means that the medal awarded for 1916 should be wrong, just a late award. Based to my knoledge, all the medals awarded after WWI should be crowned Z & F.G. All the medals awarded for Abyssinian Campaign, Spain & WWII should be of such type. il-clifton
