First established in 1849, William Conolly operated the Argyle Steam Flour Mill in Goulburn. In the early 1900s the business moved to the city's former public baths building at 285 Sloane Street, which was conveniently located next to the railway line. This location enabled supplies of grain to be received from growers, which was then milled onsite, and the finished products transported on to Sydney and elsewhere. In 1925, the addition of a 90 foot silo was announced, to store more wheat for the Argyle Mills.
