I have recently purchased a medallion which is made in two pieces, on the obverse it has a 5 pronged crown sitting on a triangle which is surrounded by a ring. If I prise it apart the medallion it has piece of red glass positioned in the centre behind the triangle and crown.
On the reverse its plain and hallmarked London, a 1924 date letter and the following makers mark - GK & S
Anyone have any ideas?
