Thanks to Peter Butler for this great picture and description:

First horse in front is War Farr (won the Wagga Wagga Cup in 1930) with Jim Smith. Steam Boiler being taken to Stinking Creek, Stoke’s Copper Mine at Goobragandra near Tumut. Dan French’s bullock team. Man in front of steam boiler is Dan French. William (Bill) Clarence Butler and Dan French were both involved in taking the boiler to the mine. The boiler is still at the mine.
Charlie Stokes had a machine like this behind his home ..( Gwen Brumbies father ) We used to play on it as kids ..
I was my great grandfather I believe.
What an interesting pic….Love to see these from decades ago.
