Wilbur,
It is very possible to build an accurate CSS Alabama from the Revell kit, but you have to use a few after-market products and conduct a little surgery. I am using the Scaledecks wood deck set for the for the pivot gun rails, I am relocating the gunports, and am using the Cottage Industry set of accurate cannons. I have also begun cutting scuppers and have altered the masts to provide the distinctive rake. The hull lines are generally close enough but those openings at the stern must be filled in. Although these conversions might seem difficult and complex, they really are not so. There are several videos on Youtube that can provide guidance it you are interested.
Gene,
Your Kearsarge is looking GREAT!
Bill
