Hmmm....The Sultana has been a rather popular modeling subject since Howard I. Chapelle published a set of plans from her (traced from the Admiralty drawings made after she was taken into Royal Navy service) in his book, The History of American Sailing Ships, which was first published in 1936. Chapelle himself drew the plans for the first release of the Model Shipways kit; he was a good friend of the two gents who owned the company. I think the kit made its first appearance in the early sixties - though I could be mistaken about that.
If I'm right, though, the Aurora "Black Falcon" hit the market before the MS Sultana did. I have no idea what the Aurora designers used as a basis for that kit. It has a vaguely generic eighteenth-century look to it, though I have some doubts about the shape of the after hull. (I should emphasize that any comments I can make about that kit are based on memories of having built it about 35 years ago, and on the most interesting photos that have been posted in this Forum recently.) Since the Sultana also has a fairly typical mid-eighteenth-century hull shape, there is indeed some similarity. There also, however, are some big differences. The "Black Falcon" has a fully raised forecastle and quarterdeck - raised so high that, if I remember correctly, they have gunports underneath them. The Sultana's forecastle and quarterdeck are, at most, a foot tall. And she doesn't have any gunports, like the Aurora kit does. It looks to me like the Aurora designers were trying to represent a considerably larger vessel.
EPinniger - if you've been bitten by the sailing ship bug and want to tackle another eighteenth-century subject, my suggestion is to take the plunge and order a Sultana kit. I think Donnie will confirm that the gulf between plastic and wood ship modeling isn't as big as some people seem to think.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
