Its an amazing place. 'About 2.5-3 football fields indoors, filled w/ antique riding/driving/flying machines. Each one there - operates, including a 1917 Curtiss 'Jenny'. 'Drip pans are under the engines for a reason. Like many museums, many volunteers are geezerly like me & have tons of stories about the planes, the designers, famous pilots.
Wot no fly-by-wire controls . I liked those days when you could see the whole plane and everything you touched had a straightforward connection to what it was supposed to control. Engineering "writ large" as they say.
Thank You, Gents. The turbine-like exhaust manifold had my attention for its shape and it appeared to be stainless that had darkened from exhaust heat. It appears to have valves enclosed by valve covers, but the visible covers shield the leading side only. The back sides have exposed valve stems & springs. They're visible on the cylinders at 1:30-2 o'clock and at the 8:30 cy. The back edges look like more of the forest of cooling fins, but are actually spring coils.
