Not a cabin, but here is an old gold mill hidden deep in the mountains with a very rare roller style ore crusher still inside.
There would have been large leather drive belts turning these pulleys and operating the various power equipment throughout the mill, all powered by a single engine.
Ore would be dropped in the top of the structure, through a jaw crusher, into the roller crusher to pulverize the ore, then onto the separation or cyanide tables to extract the gold.
