Thank you Steve, I'm undecided now that she's finished.
I'm in no way an expert on this, but to answer your question Mike, besides the obvious differences regarding the ornate figurehead and open stern, she carried a Lateen yard on the Mizzen mast, the fore and main channels are in a lowered postion, the forecastle deck is shortened, the break of the Qtr deck ends aft the main mast with light gangboards running between them.
The masts had wooldings instead of iron hoops along with a front fish, she did not carry the flying jibboom and spritsail topsail yard and dolphin striker, the elabrate entry port and a myriad of other differences regarding bitts, pinrails or lack of them, taffrail, armament and rigging etc, I chose the most noticeable changes.
As far as I know the model depicts her as she was in the Battle of Trafalger, maybe not 100% as there are questions as to whether or not she had opened entry ports and possibly extended bulwarks?, at that time. Hope that helps.
