This is a rare McCoy 40 Red Head model airplane engine. It appears this engine was mounted but I don't believe it has ever been run. You will notice the front mounting holes on this engine are slotted, this is how these 40's came from the factory. There is some small paint loss on the back of the redhead, probably shelf wear and some small chips of paint missing on the edge of the top fins. Please see the photos for condition. This engine turns smooth and has great compression. This is a hard to find engine in this condition.
