That’s a beautiful display setup!
Awesome cutaway! I can’t imagine working on that. I worked on diesels for 40 years.
My Dad was a machinist, he loved things like that engine..
When I attended AOCS in Pensacola, FL, in 1964, that R-4360 cutaway was used to teach us about “round engines.”
Several of the Unlimited aircraft that race every year at Reno use this powerplant.
The R-3350 is the more common “round engine” - e.g. Rare Bear, Super Corsair, re-engined Sea Fury, etc.
Of course, Merlins and Griffons abound!
