Anybody have the wherewithal and resources to do a fuselage mock up? Just a small section of course. Not sure what use it could be, but might prove informative in working out scenarios as to how the window hole was patched.
I believe to accomplish that, you would have to have a bill of materials and a set of working drawings. Neither of which I believe anyone has.
That's a good point for accuracy's sake, and accuracy is of course vital.
That said, as to a reasonable representation of the original structure, it is
dimensions that count the most. That includes an accurate portrayal of the outer skin - air passage - to include an accurate placement of all rivet lines, window outline and placement of associated window framing rivets. That means an accurate 'skin'; the underlying structure could be simplified by the accurate placement of plywood ring formers (the vertical pieces), and simple "L" sections for stiffeners. I think it would be good to leave the window aperture uncut, but clearly drawn, such that the artifact (or a facsimile of the flat pattern of same) could be applied.
We see this in accurate mock-ups in this industry all the time, and it works well - but it has to be high-quality / held to accurate dimensions. That takes us back to the drawings to get it right, plus, since we have no drawings that we know of for the window installation itself, we have to derive accurate dimensions from the photo evidence. I'm sure that can be done (already has to some degree by Glickman's work, apparently): it is a matter of scaling off the evident landmarks on the visible skins - rivet lines vs. known stations, etc.
Contours could be a challenge, since the Electra was graced with compound curves - but I don't think the longitudenal axis is critical here - a 'barrel' would do for a reasonable illustration as I think the vertical contour is the more critical.
A good, long weekend project for somebody. Getting accurate dimensions set to paper would be the biggest part of it and the drawings would surely go a long way toward making it possible. Short of that, I guess a real Electra could serve as a source for reverse engineering the thing.
