News report: 12th July 1913, The Mail Adelaide ….
“After long years of strenuous fighting and planning those whose brains conceived the idea of municipal abattoirs to control the meat supply of this city reaped their reward today, when what might be termed the city’s great meat shop was officially declared opened. The days of the old cattle market on North Terrace … have gone forever.”
The abattoirs had 17 ‘motor lorries’ to deliver meat to Adelaide and suburbs and the drivers were provided with uniforms. Presumably the button below is from one such uniform. The button was produced by Stokes & Sons, Victoria. Stokes also made buttons for South Australian Railways and Fire Brigades.
