Very interesting indeed. The lineage of these old kits is really bizarre. Lindberg apparently based its kit on the larger Revell one (hence such things as the coils of rope on the deck). Revell then somehow got hold of the Linberg molds - and almost, but not quite, ground the "Lindberg Line" label off the inside of the hull. And utterly screwed up the matter of the kit's scale. Weird.
The photos of the Airfix kit are interesting, too. I built this kit several times when I was considerably younger. The ones I bought (in Ohio, in the sixties and seventies) had plastic-coated-thread "shroud and ratline" assemblies, like the old Revell kits. The one in Michel's photo seems to have a little jig for "weaving" the ratlines. Maybe a little better than the original - but not much.
I've commented several times in the past about the inaccuracy of this kit's bow. Michel's broadside photos of the hull halves demonstrate what I was talking about. After looking at those pictures, though, I think I may have identified the problem incorrectly.
The problem is that the knee of the head - that is, the projecting part on which the figurehead is mounted - is too low relative to the rest of the bow. If you continue the line forming the low forecastle bulwark forward, the line should go through the head of the cherub holding the coat of arms on the figurehead. In this kit it wouldn't. I think, though, that the mistake may be not in the shape of the knee of the head itself, which seems about right, but rather in the sheer of the forecastle deck. The forecastle deck seems to sweep up in a rather dramatic curve that's at odds with reality. (A glance at a decent set of plans, or even a photo, will establish that the forecastle deck is almost - though not quite - horizontal when viewed from the side.) I think the angle of the bowsprit may also be wrong (or maybe the deck on which it's stepped is too high). At any rate, the result is that there's a big gap between the figurehead and the bowsprit, whereas in reality they're only separated by a couple of feet.
The bigger Revell kit, and the big Heller one, got that point right. (Assuming, that is, that the forecastle bulwarks of the real ship are correctly configured for 1805 - which they may not be. But that's another question.)
In listing all the small-scale Victory kits we shouldn't forget the little Airfix one. I remember building it when I was a kid. (A hardware store, called Hall's Hardware, in downtown Columbus, Ohio, had a wonderful hobby shop in the basement. Hanging on one wall of it was a rack of Airfix kits - the little ones in plastic bags. They cost about 50 cents apiece. That rack, along with a small stack of Rosebud Kitmaster locomotive kits that Hall's also stocked, gave me my first experience with non-American models.) I don't remember much about it except that it was a waterline model (complete with a rather nice "sea" base), it had injection-molded plastic sails, the flags and the stern decorations were printed on the card that held the bag closed ("Caution - Open carefully. Instructions overleaf."), and the shrouds and ratlines were printed on a small sheet of clear plastic. For its day it was a nice kit, and a great way to introduce little kids to the hobby. I believe it's still in the Airfix catalog - but I wonder if it still has the printed stern decorations and clear plastic "rigging."
