Legg's Egg is 2-3/4" wide. That is, I believe, about 70 mm, right?
I have my own thoughts on the wedge hull dimensions, which I am planning to build my third model to. You learn a lot about this filming model when you build it multiple times based on the countless photos of it, then referring back to those photos to see where you are off and by how much. When I built my second destroyer, I improved on many of the things I did wrong on the first, but then found new areas to improve.
The bridge and all the structures that proceed it on the real thing come to a length of about 23-1/2" to 24". The real thing is between 13-3/4" to 14" at its wides point. This is based on what I have been able to build so far. Mine is 23-1/2" long by 13-3/4" wide. I am giving a margin of error, as I can't say this is exactly what the real thing is, but it is very, very close. Knowing this much gives you an advantage in more closely figuring out the length and width of the wedge.
In my experience building two and a half star destroyers, I believe the length of the filming model to be between 48" and 50", and the width to be between 28" and 30". I am leaning in the direction of 48" x 30". I've already built a very accurately proportioned hull in my second replica. Even though it is at 3' long, when I go into the computer and scale it up to 48" (or 4' long), it closely matches what I have already built for the third. Any larger and it would look way off (to me, I should add). Even if it is a bit too short, it will still look right. When it is too long, that's when it becomes painfully obvious.
Anyway, There are other reasons why I believe it to be so. Actually, one of them was pictured in this thread. The one of the frame of the model on the work bench. Perhaps it was always called the 3 footer because maybe that's how long the frame is (give or take, it's not much longer)? Adding how much the nose and tail extend fore and aft from that and what do you get? I'm not saying it definitely IS 48" long. The only way to know for sure is to measure the real thing, or ask one of the ILM guys who worked on it. I plan to do one of these.
So, if you are still reading my ramblings to this point, then you are as interested in finding out as I am. At any rate, I hope this helps, or at least gives you something new to think about.
Cheers.
