Hi,
I thought I'd update everyone on this project. The Atlas kits went together really nicely, although I had quite a bit of fussy sanding and filing as I painted sub-assemblies, and the paint added a bit to the already exactly fitted parts. It really came out nicely, I think, and here's a picture. The rest of the diorama should go fairly straight-forward from this point on. I want to thank everyone who gave me some input.
Take care,
Artie
