The first thing I did was try to find his details, this is what came up...
George TREAGUS PO 14656
RND
DOB 02/11/1887 in Petersfield Hants
I downloaded his RM record and found he had been killed on 18/10/1914.
He was part of RNAS. and had been killed in an engagement in Belgium with another marine called Philip Oatley. This engagement is detailed in ‘Britain’s Sea Soldiers by General Sir H.E. Blumberg, K.C.B.
Interesting what a swagger stick can turn up with a bit of research.
