This howitzer is not recorded in the 1901 report of the Military Committee of Inquiry set up to record the state of Defence in Australia following Federation. This report does not include guns held on Fort Denison and therefore we can assume the howitzer may have been on the island at the time of the report. Alternately it may have been part of naval armaments which are not included in the report.
This howitzer is different to the other howitzers in it has no ring above the cascabel and has the insignia of Sir Richard Hussey Vivian, 1st baron Vivian, Master General of the Ordnance 1835-1841.
