Jim my friend, your post #12, I think the ship is the Mysteron Agent Scoutship from the planned Captain Scarlet feature movie. I don't know more than that, but the general design was shown as a "concept drawing" in a SciFi magazine in the late 70's or early 80's.
Why in 7 colours of heaven the ship is such a bright colour I know not, one would have thought it should have been designed in dull colours, given it's role , but your colouring is dead-on accurate as I recall the illustration.
I like the way you've designed it.
The Betty & Barney Hill ship looks very, very good, fits extremely well with my memory of the illustrations and descriptions I've seen. Well done on this one too, my friend.
The Kong model and diorama are certainly progressing well, and I'm liking what I'm seeing therein.
Kind and Respectful Regards Jim my friend, Uyraell.
