Here's more updates
The Fine Molds Engine Deck beside my (uncompleted) MPC Deck

Comparing details of Jawbox

Modified Dish....its diameter matches dimensions of Jawbox

Still more detail to add to Dish support legs, but you can see I've shortened the Cylinder base it sits on and added variants to its diameter.

The dish out of its socket to reveal the details

I've added a relief & notches around the diameter of the Turret, still to add details around the wall
