Sigh... I swear I saw that P&W Double Wasp set up recently. I've spend all evening looking for it, and I cannot remember where I saw it. Assuming I did see the same one and I recall what I saw, it was a mockup for the engine. So, a fake nacelle and a fake wing, just done to show how things could be. I remember thinking that it was an awfully long spinner. If I find it, I'll be sure to post.
