Enamelled brass disc made in the shape of a miniature crest. The crest is that of 'HMS Agincourt', which was previously called the 'Sultan Osman I', when it was in Turkish ownership. The disc is decorated in blue enamel with Arabic lettering and is surrounded by a brass rope work border, below which there is a ribbon motif in light blue enamel, which is inscribed with the name 'HMS AGINCOURT'. The crest was originally fixed onto something - possibly a box. There is a hallmark on the back
