[4] AMSCOL began with the Beauchamp brothers, who operated a milk delivery business from premises at 150 Carrington Street, Adelaide.
They were sons of John Beachim Beauchamp (c. 1830 – 7 August 1913)[5] who, in the late 1800s, left Somerset for South Australia, and after failing as farmers purchased a dairy on Junction Road, Rosewater, where the younger brothers spent their childhood.
On returning to Adelaide in 1909[6] he purchased a horse and milkcart, and soon had a "round" of 120 customers, delivering 24 gallons (110L) before 8:30am daily.
[10] A family photograph, taken at a reunion in 1926, includes the brothers Herbert, Frank, George, Walter, Harry, and Richard.
[14] The company was set up on the Co-op model, with farmers supplying more or less milk depending on the number of shares held, and being paid according to its butterfat content.
