This Muncaster Steam Engine is made from drawings and the scale is 10:1. You can use it to try your skills of animation of mechanical products. 

The model contains 100 objects. So it is possible to animate the objects that should  move in real life.

I think you will have fun to try it out.

The objects in the Blender file are parented to an Empty. The Empty has the name Container. So if you select the Container you can move all objects.

You will have a blend file, fbx, obj and mtl files.

All objects and materials comes in a zip file.
