A recent addition to my WW1 CEF collection...........unfortunately no chinstrap, but still in pretty good shape. Cheers, Keith
"Heavy Batteries RGA were equipped with heavy guns, sending large calibre high explosive shells in fairly flat trajectory fire.The usual armaments were 60 pounder (5 inch) guns, although some had obsolescent 5 inch howitzers. As British artillery tactics developed, the Heavy Batteries were most often employed in destroying or neutralising the enemy artillery, as well as putting destructive fire down on strongpoints, dumps, store, roads and railways behind enemy lines." .....The Long, Long Trail website
