This isn’t a think with an engine or motor. It is an engine. Without the thing. Or, put another ways, this thing is a steam engine.
My son used to build miniature steam engines. Not “models.” Real antique steam engines. Many of them work. They chug, whistle and make that great steam engine sound. They could be installed in an appropriate vehicle, boat or automobiles.
All of Owen’s engines were originally old and broken and required complete overhaul and restoration.
This little one was a gift for me. It doesn’t work, but it is, nonetheless, a steam engine. And it fits nicely on my mantel.
