Oak tray carved with the badge of the Royal Naval Brigades, a shield bearing a foul anchor with the initials RNB and a naval crown above. It was made by prisoners of war while interned at Groningen, Netherlands, during World War One.

The Royal Navy Division (RND) was made up of two naval brigades and a brigade of marines formed from surplus personnel from the naval reserves. After brief training the RND was sent to defend Antwerp alongside Belgian forces in the opening stages of the war. Fifteen hundred men crossed the Dutch frontier and were interned in the Netherlands to avoid capture by the Germans, the remaining survivors embarked for Dover in October 1914.
