I have seen the Pratt and Whitney logo attached to the engine case on airplanes, as well as Continental, Lycoming and other logos. But, I never thought I would see Eureka's number plate on the front of an aircraft engine!. Thanks Dave. I'm proud the narrow gauge is represented now.
By the way.....the giveaway that the number was attached to an airplane was the gray color of the parts behind it. I have worked on many aircraft engines over the decades, and I thought the color of the paint was mighty familiar from my aircraft experience.
