Nice job so far - looks real good.
I actually had an opportunity to correspond with Douglas Trumbull, a couple of years back, about the VF model. He was very open to questions, at the time, but was apologetic that no plans or detailed info on the ship survive today.
He knew of the Cinefax piece and agreed that the article they did had the most information available on the work done on producing the ship.
The kits use were mostly 1/35 scale if that helps (a Cinefax photo of a pile of tank kits show that).
Sean Kennedy did a pretty good version some years ago which can be seen
here.
