American 90-mm M1A1 Anti-Aircraft Gun, 72382 stamped on the barrel, Chevrolet, and General Motors stamped on the breech.  The left indicator regulator (M1A1) on the gun bears a plate with the serial number 19873.  This gun is on display near the parking lot.   This type of gun was used by the American army during the Second World War, but it was not adopted by the Canadian army until the early 1950s when it replaced the British 3.7 inch anti-aircraft gun.  The breech of this gun has been welded shut and the wheels used when the gun is being transported have been removed.  Fort Rodd Hill National Historic Site of Canada, Colwood, British Columbia.
