Finally got back to this.
I shelved it while amassing ref material, then got stuck in the weeds planning all the corrections.
With the new, super detailed kit coming out, the idea that this'll be displayed hanging out of sight anyway and that I desperately need something in the win column, I decided to just plow ahead.
I cockpit and wind (space) screen were wildly inaccurate, but I'm not going any further than I where I left it. I made a pattern to vacuform a properly pitched screen, for some reason they went vertical on the kit which isn't even remotely close to the filming model. I was having a hard time getting a good pull previously, but got lucky of the first try now, a guess that's a sign I should be doing this now.
Second was lack of detail on the outside front deck. There are ribs and a lip that I cut a glued using strip stock:
Here's a test fit of the windscreen angle:
And finally, I originally was going to go nuts with the interior, but I decided to just solder together the Paragrafix PE and plow ahead. There are simple chairs and a box with detail. I'm not sure I'm going to spend too much time on it, originally I was going to sculpt a 1/144 Poole and Bowman and toss in a few LEDs
Just some cleaning up here and I have to work out the window frame, but otherwise it should be straightforward after the sphere is closed up.
