Zilles Printers was begun by Lewis Zilles in the early 1930s. It was in McKenzie Street Ballarat. His son Jeffrey also became a printer - letterpress, offset and screen printer. The business became Zilles Printers/Graphics and was in Armstrong Street and later Bell Street Ballarat. The Bulldog Engineering Company emerged around 1886. J Abraham began the operation building windmills and pumps. An employee, J F Osbourne, purchased the business when Abraham died in 1914. Windmills were still produced but Osbourne began to manufacture the "Bulldog" oil engine towards the end of the first world war. The Bulldog engine production was around 400. Of these there were 40 with wavy spokes. Some writer have been using Ballarat Bulldog as the brand name. This is incorrect, it was just Bulldog, made in Ballarat.

In 1943 Australian Army engineers; the 2/1 and 2/16 Field Company RAE, 9th Australian Field Company (AIF), veterans of Syria, Palestine, Egypt, Greece and Crete, the 1st and 3rd Australian Pack Transport Companies and local Papuan labour cut the road with pickaxes and dynamite over a period of eight months. During five months of operations over seventy per cent of the 2/1 Australian Field Company contracted malaria.Seventeen bridges were constructed; mostly single, but at least one with multiple spans. More than two thousand Australian army personnel and over two thousand Papuans and New Guineans were involved during nine months of construction. Thus the road, acclaimed as the greatest military engineering feat ever, was completed and for the only time in history motor vehicles crossed the high rugged mountains of Papua New Guinea.
