Coat of Arms of Coucy - messengers badge?

[AHorsa]

Thanks for your comment Fernando and happy to hear that you also have no doubts on its age. A very nice example of an astonishing preserved medieval belt you show!

I just searched the net for medieval depictions of knights, noblemen, horses etc. but couldn´t find something fitting. But what I´ve found again is this depiction of a messenger, althogh it is German and 15th century. For me this is still a possible usage of this shield. Will keep on searching
