There are several questions that maybe should be addressed here. One is the "heritage" of that Aurora Sea Witch kit. We've had several discussions about various representations of that ship here in the Forum recently. I'd always assumed that there was only one Sea Witch in plastic, and that it had appeared at various times since the early fifties in at least three different boxes: Marx, Aurora, and Lindberg. Recently I've started to have my doubts. I think the Aurora one may have been a completely different, smaller kit. But I'm honestly not sure.
I have the general impression that Monogram acquired Aurora's molds when the latter company went out of business, and that they eventually passed to the Revell-Monogram label. Recently the name "Monogram" seems to have disappeared from the Revell website. Logic suggests that Revell USA now has the Aurora molds, but that's just surmise on my part. The manufacturers don't seem to like talking about such things. And so far as I know, those four medium-sized Aurora sailing ships (Sea Witch, Bonhomme Richard, Wanderer, and Hartford) have never been reissued by anybody since their original release (unless the Lindberg Sea Witch is in fact the same kit - which I doubt).
I bought the Aurora one a very long time ago, when it was new, and had big reservations about it. I'm sticking my neck out here; my aging memory is far from the most reliable. But I think I remember that the sails were injection-molded all right - but that they were astonishingly similar in shape and detail to the vac-formed ones of the Revell Thermopylae. In other words, they were made like vac-formed sails, but a whole lot thicker. The "seams," "reef points," and other details that were molded into the original vac-formed versions appeared the same way on the injection-molded copies: as raised lines on the fronts of the sail and grooves on the backs. To my eye that arrangement looks silly on a vac-formed sail and downright ridiculous on an injection-molded one.
The other problem with those hugely thick, injection-molded sails is that they're extremely heavy. I never tried seriously to rig such things to a model, but every single photo of a finished model with injection-molded plastic sails that I've ever seen has suffered from the same problem: the weight of the jibs and staysails makes the supporting rigging sag to a degree that is, to say the least, extremely unprototypical. I suspect that if the stays were set up taut enough to keep them from sagging, they'd bend the masts out of line.
To each his own. A careful paint job could, I suppose, camouflage at least some of the drawbacks to injection-molded sails - at least when viewed from some angles. And maybe the judicious use of wire for some crucial rigging lines could solve the weight problem. But in this particular case I'd strongly recommend getting a good look at the kit before paying any significant amount of money for it. It's entirely possible that my memory is playing a trick on me, but if I'm right about those "grooves" all over the backs of the sails I don't think many serious modelers would want anything to do with them.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
