Manufacturing Naval Guns and Mountings
This April 1945 photograph of the Canadian Pacific Railway's Ogden Shops in Calgary, Alberta, shows 4-inch naval guns and their mountings.
The Ogden Shops produced two types of 4-inch naval gun mounts, which were installed on warships, while the gun barrels themselves were produced elsewhere in Canada. The shops produced naval guns for American, British, and Canadian ships, manufacturing more than 3,000 naval guns and 1,650 naval gun mounts. The 4-inch gun was the largest artillery piece produced in Canada during the Second World War.
