^ Hey, those are mine! I made them about 8 years ago (can that be right??) The stack of reference material on the left is a collection of images culled from the interwebs. It contains screen caps, pix of the 11 footer in the Smithsonian, other people's analysis, etc. I would be more inclined to send you the images rather than print them out. Obviously, none of the images are "mine" so I can't take credit for them.
FYI, while not a bad model, I modified or replaced literally every part on it to get it accurate enough for my taste. The booklet on the right in that image is a summary of the major changes I made. I also made all of my own decals. And, even though I made decals for them, I actually painted pretty much all of the underside markings including the triangles on the bottom of the saucer & the circle-tee-rectangle-square on the secondary hull.
BTW, as others have mentioned, pencil in the grid lines after you've completed assembly & painting. Pencil is awesome because you can wipe off your mistakes. Use a compass for the concentric circles. A trick I learned for straight lines on compound surfaces is using Dymo Label tape. It's sticky, so it stays in place & it's thick enough to scribe or draw along. I also installed the clear dome before I drew the circles -- I just protected it with a stack of about 10 small squares of masking tape.
If it's helpful, here are the pages from the booklet:
Good luck & if you have any questions, don't hesitate to ask!
