The ONLY one I could find that was close to accurate was Conway's 4.1 version
Falcon DeAgo Cone v4.1 by ralph_conway on Shapeways
I purchases the cheaper "white processed versatile" plastic and primed it with tamiya grey spray, brush painted a couple of coats of mr surfacer 500, 360 sanded, surfacer 500, 360 sanded, two brushed coats of tamiya acrylic, sanded and matches the deago parts nicely. Excellent fit.
All others the window frames do not line up properly (the front radial window frames should not line up with the tapered cone window frames). I nearly purchased the 308 bits cockpit but shape issues stopped me: the cone windows go right up to the front ring (too far, makes the windows look too long and shows a heavy stepped window frame when viewed from the front, the radial window frame lines up with the cone window frame, bottom cone window looks too rectangular to my eye.)
