Is anyone aware of a good source for ship plans or construction drawings for Civil War era ships? I'm particularly interested in USS Kearsarge, USS Hartford and Brooklyn. I'd also be interested in knowing if any plans exist for some of the better known Confederate Commerce Raiders, not including CSS Alabama. For instance, I'd like to know if plans are available for CSS Florida, CSS Sumter, CSS Shenandoah and CSS Georgia.

Any help would be appreciated.
