The gun stood in front of the entrance way to the Officers mess at Victoria Barracks and has suffered from over frequent polishing and the markings had become faint. This practice ceased years ago and the gun placed indoors at the Army Museum Sydney. It is highly likely that the 6 pounder brass gun at Victoria Barracks is one of the guns emplaced at the redoubt in 1788 and hence is of very high significance to the history of European settlement of Australia.

The first recording of brass SBML 6 pounder guns appears in 1788 when two were emplaced in a redoubt near present day Macquarie Place, Sydney. By 1801 there are four 6 pounder brass field piece guns recorded. Two at Barrack Parade and one each at Sydney Guard House and Parramatta.

Several guns of various weight and length were produced. A ‘brass’ 6 pounder gun, designed by William Belford, was introduced in the 1770’s was a light piece of 5 ft, weighing about 5½cwt.
