Unknown continental mark - your help needed

This is a brooch in the form of a shield. It has 925 WITH WHAT LOOKS LIKE A LARGE SQUIGGLY M NEXT TO IT. It also has a seperate hallmark which reads F.E. 925 FOLLOWED BY A SYMBOL I CAN`T RECOGNISE AND THE LETTER Z. Any ideas ?

Can you get a better picture of the smaller set of marks? I suspect they may be modern British marks.
