London as a fire brigade has had many badges since its inception in 1904 after the name change from M.F.B ( Metropolitan Fire Brigade ) to L.C.C L.F.B ( London County Council London Fire Brigade . This particular badge represented another name change when the brigade merged with its surrounding neighbours in 1965 adopting a new name of G.L.C L.F.B ( Greater London Council London Fire Brigade ).
