Forgot to say 38ac, the engine has a brass plate stating it was sold by Winchcombe Carson, Brisbane, so I know it was probably used in the wool industry, in some form. As it has the exhaust configured horizontally, I don't think it would have been on a shearing plant, as they have a vertical exhaust, to get the fumes away from the shearers. My interest in shearing plants was raised by me obtaining a 1927 Coopers plant, and my memories of my father shearing up to 2,500 sheep on the family farm when I was knee high to a grass hopper.
