From Cornflakes to Beaufort gun turrets

The Beaufort was a twin-engine aircraft designed for torpedo or bomb carrying and produced by the Bristol Aeroplane Company Ltd. At the start of World War 2 these aircraft were made with both local and imported parts. As the war progressed, the plane had to be manufactured entirely from materials and components sourced within Australia, and so the Beaufort Bomber became the first purely Australian-built aircraft.
The manufacturing and production processes were spread across three states, with 600 companies involved in what must have been an extraordinary logistical feat. The heavier manufacturing processes took place in selected railway workshops. 
A factory in Fairfield also played an important part of this project.
Shortage of gun turrets and armaments from overseas led to the development of a gun turret annexe in Fairfield. The Department of Aircraft Production (DAP) selected a factory building located at 159 Heidelberg Road, Fairfield which was producing Cornflakes breakfast cereals before the start of the war.
Work began on the gun turrets at the Fairfield plant in the expectation it would take up to 2 years to produce the first locally manufactured turret, but this was achieved in 6 months.
An article in The Age explains that of the total work force across Melbourne working on the Beaufort planes, over 80% were men and women without previous factory experience. Training centres in NSW and Victoria ‘converted butchers, bakers, clerks, hairdressers and even women who had no experience beyond household duties into efficient units on the production line’.
The men and women who are building Beauforts come from the stage, the circus tent, the bake house and the bar room. The division employs a pastry cook who helps to make ship busters now instead of doughnuts’.
In 1944 The Age mentions distinguished service awards for pilots in the South West Pacific area and asks the question, ‘How many people recall that these Australian airmen won distinction while serving in Australian- built machines? The story of the planning and building of Australia’s great fighting plane, the Beaufort, is one of which every Australian may well be as proud, as are the men and women who turn out these famous machines’.
During the war years the Fairfield factory increased its range not only to different types of turrets but also undercarriage support beams and hydraulic components for other aircraft.
At the end of the war and with a reduction in the manufacturing of aircraft, the operations at Fairfield were stripped back, but DAP staff were still working at the building in some capacity for several years later according to street directories.
The building is now operating as a self-storage facility.
