Some progress:
Here are the contents of the Haitian rebel ship package - hulls, masts, bowsprits, funnels, and deck guns! Fortunately, there are good pics of the assembled models on the FB page, and line drawings in the Salnave's War book. Phil (of Spithead Miniatures) also sent a helpful e-mail detailing some of the differences he decided for the models, and suggested painting guides.
After a bit of sorting, the models are ready for assembly. I need to review my basing plan before going much further.
Last but not least, the government squadron is sorted.
