R.M.Williams - The Longhorn Brand. It was during the 'Great Depression' of 1930 that the founder of the company, barely 20 years old at the time, earned his living in the deserted outback of South Australia. Here he worked in surveying teams and as a well digger. At the large Outback Stations and Cattle Camps, R.M. later learned leather crafts and many other Bush skills. Around 1930 Reg Williams began manufacturing saddlery and boots in No. 5 Percy Street, Adelaide. The Longhorn became a trademark for fit, quality and durability. R.M. Williams became an Australian legend.
