Photo made in 1997, but I'm thinking the a/c is now at Pima. There's some debate about "the cylinder" - as several A&P mechanics have noticed the cylinder is a "front" cylinder, but it's popping up where "rear" cylinders are located in the engine. A joke for the visiting public? Might explain Paul's comments about prop feathering and oil spills. hmmmm
