CEC VCX-820 Courier
was originally designed by Jeff Carlilse as part of one of his official
roles illustrating for Wizards of the Coast. I have the very great pleasure
of counting Jeff amongst my friends which has provided me with two great
advantages in deckplanning his ships; Jeff has always been very happy
to wax lyrical about the internal structure of the ships (whenever he
has taken the time to think that through) and he has almost always been
happy to provide sketches of various ships where certain details have
been unclear on the main illustrations.
On the other hand it also has an X designator, meaning it IS a one-of-a-kind concept model.
