For sale is a collectible Madewell .40 model. 

The name of the engine may be Madewell but with the pitting it is difficult to read.   The fuel adjustment value works.   Also difficult to read is the displacement it may be .40.  The cooling vanes on the engine do not look bent and appear to be in good condition.  There is also an old spark plug in the engine.

Great engine for a collector of model engines.
