This Modern 3 Blade Windmill is a nice "O" or "S" gauge size precision layout accessory that is completely assembled and ready to use.
It runs off two AAA size batteries & has an off / on switch. When operating it gives off an industrial rumble from the contained motor. Sounds like a turbine generating power.
The tower stands 8" Tall and is 11" tall at the tip of the blade. Very nice construction, fully assembled, detailed, painted and ready for use on your layout. Not a kit! Ready to use!
