Featured Help Identifying Toy Steam Engine

Hello. I recently purchased a few toy steam engines at an estate sale and I would like some help identifying one of them. The only mark on it is on the bottom and it says made in Great Britain. I do not know if what I have is complete or whether it is operational. Any help would be greatly appreciated

A few similar ones. I don't think pinning down the maker is going to matter much. It will sell based on what it is.

 

Might be part of a Mamod one.

 

Hello,
What you have their is a hot air engine made by Charlton Davis.
I'm not sure if the wick is still present with your engine but as you will see from the photos below yours is missing the black dome "oven".
If it is working I would think it would sell for $50 (give or take).
One seller stated that they used a propane torch to test the engine.
I have included some screen shots from my research.
Also, here is a video of a hot air engine in action (made by Pheonix).
