Can anyone tell me about a badge. It's a 1910 First General Efficiency and Gun Practice badge, brass and inlaid dark blue enamel. It has a large blue 8 in the centre, with a blue enamel circle around it saying Battery 4th H.B.C.G.A on a brass maple leaf with Canada in blue enamel underneath. The circle round the outside has the words First General Efficiency and Gun Practice and the year 1910. Cheers, Recz
