Perfect for your steel mill model. Cobble together some proper blocking and take it for a spin around your layout. We can't tell if it's part of a crankshaft of a container ship, flywheel for a moon rocket, clutch for some huge piece of machinery or ??? One thing's certain, it'll be fun to finish this out in a metallic paint job and roll it out of your steel mill to your customer's factory site or shipyard.
