 By the end of their active use in 1902 together they had fired 1540 rounds in practice , though not all at full power as they are recorded as firing under 300 effective full charges . By then the wheels were significantly rotted and the ammunition limbers had become unserviceable . Less wheels , the guns were removed from the fort in 1909 ; Adelaide 's city council then set them in Brougham Gardens , North Adelaide . Both were returned to the fort in 1976 and remounted on restored carriages of the original design . They are the only two guns of their type remaining in Australia . The southern gun ( Number 463 ) fired three blank charges in 1980 to mark the centenary of the first firing at the fort . This same gun is fired regularly by the volunteers of the Fort Glanville Historical Association ( FGHA ) .
