Trying to establish what this badge was for we have found it in a relatives possetion hope i can describe it correctly here goes ....
a silver triangle shape with a crown in the middle , under the crown is the date 1916 , in the triangle edges are ON WAR SERVICE , at either side of the triangle are 2 circles in white enamel with the letters N P , then at the bottom of the triangle is like the bottom of a heart shape with a letter F in the enamel with 1699 underneath
The badge does appear to be 2 peices as the triangle is placed on another underneath "bit"which then has a T and S at either side of the crown ...oh dear i do hope i have done justice to the description

any suggestions would be most appreciated .
gah
