Re shrouds and ratlines - I'll accept CrazedCossack's invitation to refrain from another diatribe against that ridiculous jig/loom gadget, and try to explain two extremely old-fashioned, but far better-looking, ways to do it - as modified slightly for use in plastic kits.
The first step is to set up the shrouds. For that, in the case of the Heller Victory kit, I strongly recommend ditching the plastic, grooveless deadeyes in favor of aftermarket parts, either metal (www.bluejacketinc.com) or wood (www.modelexpoonline.com). The rigging of the deadeye lanyards is, for me at least, the trickiest part of the job. Some folks have had success with simple jigs to hold the deadeyes the appropriate distances apart while the shrouds are seized to the upper deadeyes and hove taut. But I'm afraid there's no way to make that part easy.
Once the shrouds are in place, you need to make yourself a simple guide to the ratline spacing. Different sources give slightly different spacings - anywhere from 11" to 16". Take your pick. Cut a piece of stiff, white paper or cardboard to fit just inside the shrouds, between the channel and the bottom and the masthead at the top. Draw a series of horizontal lines on the paper at your chosen spacing. (Or use your computer.)
At this point you have a choice. Before making it, understand how the real thing was rigged. On the real ship, each end of each ratline has an eyesplice worked into it. The eyesplices are seized with light line to the foremost and aftermost ratlines, and the ratline is tied around each intervening shroud with an extremely simple knot called a clove hitch. So far as I know, nobody has ever attempted to make the hundreds of necessary eyesplices in fine thread that would be necessary to replicate all that on a 1/100-scale model. In deference to practicality (and the limited time granted us on the Orb), some simplification is necessary.
Probably the best compromise between accuracy and practicality is to tie each ratline around each shroud with a clove hitch. (The clove hitch is one of the simplest of all knots; learning it takes about a minute. Knot-tying is notoriously difficult to describe verbally, so I won't try; any website that contains pictures of knots will show you how to do it.) Start at the bottom. If you're right-handed, tie the first ratline around the lefthand shroud at the point where the line on your piece of paper tells you. (Starting at the left is, at least, easier for me.) Then tie it to the next shroud, and so on. Put a tiny drop of white glue on the first and last knots, for safety, and when the glue's dried snip off the ends with a small, sharp pair of scissors or an Xacto knife.
I find the finished impression is a little better if on the first and last shrouds, instead of a clove hitch, I use a reef knot (aka square knot). That creates a little visual difference between those two knots and the others - not enough to make anybody think I actually made all those eyesplices, but at least a difference.
Method two is the "needle-through-the-shroud" method. For this one, get yourself the thinnest, sharpest needle you can find at your local sewing store and load it up with the finest thread you can get. (It's unlikely that you'll make the ratlines too thin. We've discussed the question of color elsewhere.) With this method I find it easier to start with the righthand shroud. (I'm right-handed.) At the point indicated by your paper guide, shove the needle right through the middle of the first shroud, and through each of the others in sequence. As before, put a tiny spot of white glue on the first and last intersections, and trim off the excess thread when the glue's dried. Initially you'll probably find it a little awkward to shove the needle through in the oppposite direction, but once your fingers get the hang of it you'll probably find the job goes quicker if you put a couple of feet of thread through the needle and zigzag back and forth - the first ratline from right to left, the second from left to right, etc.
As you can see from any batch of photos of models, there's just no substitute for individually clove-hitched ratlines. But the "needle-through-the-shroud" method, done carefully, can produce extremely neat, clean results.
As I've preached more than once before, I urge everybody to try the "clove hitch method" first. Most modelers are pleasantly surprised to discover that it isn't as hard, or as time-consuming, as they thought. Give your finger muscles a fair chance to get some practice with it; don't give up after the first try. I firmly believe that most modelers, if they have enough dexterity to build and rig such a model at all, have what it takes to rig ratlines with clove hitches. Such things as arthritis and close-range eyesight can, however, create problems. If it does prove too much for you, try the "needle-through-the-shroud" trick. It's a little easier, and considerably quicker.
Re plastic kits of the Victory in her as-built configuration - folks, I hate to say it, but I fear you dream. The economics of the plastic kit industry are such that manufacturers aren't impressed with the opinions and aspirations of dozens; they think in terms of thousands. That's why, as of 2006, the plastic sailing ship model kit business is almost dead. The chances of any manufacturer releasing a kit that duplicates, in subject matter, half a dozen that already exist are just about zero.
And in all honesty, there are quite a few subjects that I personally would give a higher priority. How about a 1/96 (or 1/00) H.M.S. Prince? Or a Sovereign of the Seas? Or a Wasa? Or an American clipper ship? Or a good, state-of-the-art American whaler? Or a British frigate? Or some American sailing warship other than the Constitution? (I'd be willing to bet that "new" Constitution from Revell Germany is just the old one in a different box with a higher price. That company is notorious for botching up its descriptions of scales and measurements.) I could easily make up a wish list of twenty or thirty subjects - but the sun is going to rise in the west long before any of the manufacturers asks for my opinion.
I do find myself wondering whether anybody who works for Heller, Revell, or Airfix ever bothers to look at forums like this. Personally, I've been pleasantly surprised by the number of folks who are working seriously on plastic sailing ship kits - both currently-available ones and golden oldies that get bought at swap meets and via e-bay. That Chumster website suggests that the number of purchasers of the Heller/Airfix 1/100 Victory is actually pretty substantial. Maybe, one of these days, some adventurous model company executive will decide to take a risk and put his/her people to work on a new, large-scale sailing ship kit - an accurate, well-conceived one that (a) can be built to an acceptable standard by a reasonably dexterous newcomer and (b) can serve as a starting point for the more experienced modeler who wants to turn it into a more serious scale model. That fine Japanese company, Imai, proved that it could be done - but went out of business. The Russian firm Zvezda issued a medieval Hanseatic cog a few months ago that, though I haven't bought it myself, appears to be a well-designed, reasonably accurate kit - and an excellent newcomer's project. (I'll be interested to see what else comes from that stable.) I think the other manufacturers are assuming that the market for such kits just isn't big enough to justify the staggering expense of producing them. But maybe, just maybe, things are changing enough to tempt one of them into taking the plunge. I sure hope so - but I'm not holding my breath.
