 In the late 20th century the fort acquired three 16 @-@ pounder RML mark I field guns . They were formerly used by A battery , South Australian Volunteer Artillery from 1880 until 1901 . Gun number 288 is complete and used for blank firings by the Historical Association . Also acquired is a 2 @-@ pounder RML Whitworth mountain gun made in 1867 . It was also used by A Battery , subsequently by Fort Largs as a signal gun . It is one of only two of this type known to exist , the other in the United Kingdom . The visitors centre has two 9 @-@ pounder brass smoothbore field guns made by H & C King in 1819 . They arrived in South Australia in 1857 and were used for practice shoots near the fort c.1860 ; one is known to have been on the manning parade in 1890 though its use is unknown . They later became saluting guns at Fort Largs , moving by 1919 to near the Jervois Wing of the State Library of South Australia . The Art Gallery of South Australia saved them from a 1941 wartime scrap drive and mounted them on reproduction naval carriages in front of Government House in 1962 . The gallery took them back in late 1977 and transferred them to the History Trust of South Australia in 1988 . The History Trust has loaned them to Fort Glanville for display . Outside the visitor 's centre is a 6 in ( 200 mm ) breech @-@ loading Armstrong 80 long cwt ( 4 @,@ 100 kg ) gun ( No.4242 ) that was made in 1884 and used in Victoria . The Commonwealth Scientific and Industrial Research Organisation ( CSIRO ) brought it to the state in 1966 for research , subsequently moving it to Perry Engineering at Mile End . In 1984 the CSIRO donated the gun to the park .
