This badge is very complex; like military orders and breast stars (made of several parts cast or die stamped in high relief). High-end jewelry is sometimes made of several parts, too. If there is enamel on those parts to be attached when the whole badge is assembled hard soldering is impossible because high temperature destroys the enamel. Therefore, different parts can be fixed with prongs or rivets (as seen e.g. this rare Monaco Order of Saint Charles made of silver, gold and enamel assembled with both prongs and rivets - my arrows).Even maker`s plaque is attached with prongs (Halley, Montpensier of Paris France).There is no alternative unless one wants those parts glued or soft soldered with tin-lead which certainly makes no sense when dealing with precious metals.
In conclusion: the badge shown here is extremely well made, it is genuine and intact.
