Very interesting! I built the Revell Constitution a couple of times, longer ago than I care to think about. None of the kits I bought had the mounting method Mr. Gonzales describes. The stands consisted of two oblong pieces of wood-grained plastic with diagonal props at their ends and rectangular holes in their centers. Tabs molded into the bottom of the hull halves fit in the holes. To my eye that mounting system was all wrong for that particular ship.
Between 1978 and 1980 (the dates come from Dr. Graham's Remembering Revell Model Kits) Revell marketed its big Constitution and Cutty Sark kits as a "Museum Classics" series, with Philippine mahogany baseboards and brass-plated plastic pedestals. Putting two and two together, I suspect those sockets for nuts got added to the molds at that time. I wonder whether all Constitution kits sold since then have had that feature. (Do the ones from Revell Germany come from the same mold - or a duplicate that got shipped to Europe before the mold was modified? I have no idea.) And I suspect some pre-1978 kits are knocking around on e-bay.
Mr. Gonzales's comments illustrate beautifully the problem I was talking about earlier. Changing the mounting system of a model can make it look almost like a different ship. If you do decide on pedestals, the height, diameter, and number of them (two or three?) are all crucial - as is their location. If they're placed too far apart, the model will look like it's on the verge of sagging in the middle. If they're too close together, it will look unstable. I've also seen nice models that look incredibly awkward because their mounting pedestals are either too far forward or too far aft. (I saw a picture of one in a magazine with the aft pedestal just forward of the rudder and the forward pedestal just forward of amidships. The poor ship looked like it was about to take a nose dive.) What frequently happens, I think, is that the modeler doesn't think about any of this until the model is almost finished, and by that time he's so sick of it, and has been staring at it so long, that he's either lost sight of the model's basic aesthetics or doesn't care about them any more.
The best I can offer in the way of pictures is my little model of the frigate Hancock: http://gallery.drydockmodels.com/hancock . It's a scratchbuilt model on 3/32"=1' scale, with an overall length of about 18" (about half the size of the Revell Constitution, in other words). I don't claim the mounting system of this model is perfect by any means, but I did work on it quite a bit and after looking at it for twenty years I'm still pretty comfortable with it. I got some help with it from my father, who was a professor of architecture and had excellent old-fashioned training in such aesthetic matters as scale and proportion. (He also had a superb eye for proportion - and if he thought something could be made to look better he didn't hesitate to say so.) He and I sat down one evening with a copy of the ship's plans and figured out how high, how fat, and how far apart the pedestals ought to be. Dad then drew the basic profile for me (he described it as a "classic" column shape, frequently used for such things as stone balcony and bridge railings), and I turned the pedestals on my faithful Unimat.
All this happened before I started carving the hull. For this model it was especially important to work out the mounting system early, because the ship's keel has quite a bit of drag and the forward pedestal needed to be considerably taller than the aft one. It's easy to work out those dimensions by drawing the pedestals on the plans - and extremely difficult to do it right after the model's finished. (More than one model has gotten mounted with its waterline on a slope for that reason.) One of the first things I did in the actual construction process was to drill the holes for the pedestals. While I was working on the model I mounted it temporarily on wood blocks, to keep the pedestals from getting scratched, but having a means of fastening the hull down securely made life a lot easier throughout the six years I worked on it.
The model normally lives in a plexiglas case (which is why it's still in near-new condition); the screws that mount the pedestals go through the walnut-veneered plywood baseboard. For the photos I ran a paper backdrop under the ship, punched two holes in the paper, and screwed the pedestals down to a piece of plywood.
Here's a model (1/8"=1' scale) of the New York pilot boat Phantom, based on the resin-hull kit from Model Shipways: http://gallery.drydockmodels.com/phantom . The base is a simplified version of a set of launching ways. The kit came with something similar, in the form of a bundle of basswood strips and an illustration. I liked the idea but didn't like the basswood, so I made my "launching ways" out of maple. To give a slightly more realistic impression (though this isn't by any stretch of the imagination a scale model of a real set of launching ways) I dressed it up with styrene "nut bolt and washer" castings from Grandt Line. I'm pretty happy with the results - but my wife isn't. She thinks the model would look better on a pair of simple brass pedestals. Maybe she's right. Like I said earlier, personal taste has a lot to do with this sort of thing.
Think it all out carefully - as early in the building process as possible. Take a look at how other people have done it. (If there's a maritime museum within driving distance it can offer all sorts of ideas.) Get a notion in your head of how you want the model to look when it's done. Trust your eye; it's as good as anybody else's.
Hope that helps a little. Good luck.
