Hi -
The Bonhomme Richard was a French East Indiaman, originally named Le Duc de Duras. Over the past two hundred years ship modelers and other enthusiasts have spent a great deal of time trying to figure out what she looked like. Nobody has ever discovered a set of contemporary plans, and the few contemporary paintings are so vague as to be useless.
The late Howard I. Chapelle, long-time curator of maritime and naval history at the Smithsonian, once wrote an article for the Nautical Research Journal called "Ship Models That Should Not Be Built." He put the Bonhomme Richard close to the head of the list. Chapelle's argument was that, since the reliable information is so meager, it's just not possible to build a respectable scale model of this ship.
For the opposing viewpoint, take a look at the works of Jean Boudriot. He's a French maritime historian who's produced a series of magnificently-illustrated books on vessels the eighteenth- and nineteenth-century French navy. One of them deals with the Bonhomme Richard, which Boudriot has meticulously reconstructed on the basis of what contemporary information about French East Indiamen he was able to locate. (He found, for instance, the hull lines of an Indiaman from the same date, built in the same yard.) I suspect they're out of print, but you might find used copies through Amazon, Barnes and Noble, or bookfinder.com. Be warned: they're expensive. If you live within convenient distance of a good library, you might be able to get them through interlibrary loan. I'm pretty sure the library at East Carolina University, where I work, has a copy of at least one of them - and participates in the interlibrary loan service.
I remember both the Pyro and Aurora kits pretty clearly. I'm afraid neither of them came close to meeting any reasonable definition of the term "scale model." The Pyro one was about six inches long, and the Aurora one had injection-molded "sails" (about six scale inches thick) molded integrally with the yards.
Hope this helps a little - and isn't too discouraging.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
