For the sky scope I've been using brass tube.
For the attack scope, I shave off the kit "stands" and wrap a piece of evergreen strip around the base. I then take 1mm thick plastic and wrap that around the evergreen. Putty and sand the seam. Sand the base down til it's the right height. I then add a 1mm disc at the base.
The yellow striped CT is mostly stock with scratch and AM additions. It started as out of box, but I couldn't help my self.
I have seen the Nautilus Turm II. Not bad. Good base to work on.
I wonder what the Revell one will look like.
Take Care and thanks,
