That website lists four sailing ("Aifix Classic") ships: the Cutty Sark, Victory, Bounty, and Wasa. All of them certainly appear to be the good ol' Airfix kits, which were about 18 inches long. And all of them are marked "out of stock."
That website is brand new; as of a couple of days ago, keying in "airfix.com" only got you an invitation to register, so you'd be notified when the new site was up and running. I think it appeared in its present form yesterday. That's great news. The company quite clearly is struggling to get back on its feet after a pretty horrendous financial crisis, and the website may well be experiencing some teething troubles. I suggest we cut Airfix some slack, and be glad that those kits are coming back. The Wasa, in particular, is one of my favorites.
I do hope the 1/100 Victory gets reincarnated too. I've mentioned elsewhere in this Forum some of the rather conspicuous mistakes from which it suffers. (It's probably too much to hope that the new Airfix proprietors will include a new sprue containing some means of fastening the yards to the masts. But maybe - maybe - they'll see fit to prepare a new English-language instruction book, written by somebody who understood French and made at least an attempt to build the model.) As such things go, the problems in that kit are pretty minor - and eminently correctable by a competent ship modeler. In my personal opinion it is, with the arguable exception of the Calder/Jotika 1/72 wood version (which costs about $1,000), the best rendition of the Victory in kit form - plastic, wood, or otherwise. For it to disappear from the market would be a real shame.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
