To my knowledge no manufacturer makes aftermarket detail parts that are designed specifically for plastic sailing ship kits. (The market just isn't big enough.) There are, however, several that make parts intended for wood kits or scratchbuilt models - and in many cases those parts are just as applicable to plastic kits. One of the best is Bluejacket Shipcrafters (www.bluejacketinc.com). The biggest probably is Model Expo (www.modelexpoonline.com). The latter sells a mixture of American and European fittings; they range in quality from excellent to overpriced, toylike garbage.
The kit Lindberg sells under the name "Jolly Roger" is a reboxing of an old, 1960s vintage kit that was originally the eighteenth-century French frigate La Flore. The one Lindberg now calls "Captain Kidd" is another reboxing. It was originally a German, two-decked, late-seventeenth-century warship called the Wappen von Hamburg. In their original guises, both of them were pretty good kits - especially in view of their age. But the "pirate ship" connection is nothing more or less than a marketing stunt; it's highly unlikely - if not downright impossible - that any actual pirate ship ever looked like either of those vessels.
Incidentally - and I hope nobody takes any offense at this - the term "tall ship" isn't used by serious ship modelers or ship buffs. It originated as another marketing ploy; it doesn't have any real meaning. I think it dates from the hoopla over the "tall ships race" that coincided with the U.S. Bicentennial celebrations of 1976. "Tall ship" has about the same effect on an experienced ship modeler that "choo-choo" has on a serious model railroader.
If you browse this forum you'll find several interesting threads dealing with those kits. Several folks have turned them into extremely impressive finished models. Several folks have used La Flore as the basis of conversions into their versions of H.M.S. Surprise, the British frigate that featured in the movie "Master and Commander." (There actually was an H.M.S. Surprise, and she was a captured French frigate. The ship in the movie didn't look much like the real one - or, for that matter, La Flore - but some skilled modelers have made some excellent Surprise models out of that kit.
Good luck. It's a great hobby.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
