There should be a b/w picture of the underside of this baby available in a bookstore near you. It's in one of the "unauthorized" Trek compendiums ("Voyager A-Z" or something silly like that), a small book printed on cheap paper yet sporting some pictures I've seen nowhere else. It probably still sits on a shelf in a sf/fantasy bookstore near here, since it definitely isn't worth buying for more than that single picture... I'll have a look next week.
Essentially, the shot shows the model from side, 45 degrees down, sitting on its pedestal on a shelf of some sort. There are two phaser strips on the primary hull underside, and some minor additional detail (no aeroshuttle IIRC). The deflector is roughly of the final shape, even if merely painted in, and I seem to remember the two torp tubes being in place on the upper corners, too.
Or then I'm dreaming it all up. Save for the fact that the photo does exist.
