Sure is looking sharp!
I'm really curious to see how Mr. Arnold tackles the nacelle end-cone fit problem; seeing as they're almost precisely part thickness too big in diameter, it's going to be one tough fix!
Something I've been thinking of doing is cutting the cones longitudinally into several sections and gluing them back together, hopefully preserving some detail and contour, and avoid
monumental amounts of filling, sanding, and attempting to restore detail...I'd never get those rivets right.
