Does anyone have a copy of the publication: Allen R. Saltus and Sidney H. Schell, The CSS Huntsville and CSS Tuscaloosa Project. Mobile River. Alabama (Mobile, Ala.: U.S. Army Corps of Engineers, 1985? This is the only published documentation I can find on the 2 ironclads.
I have also located a midsection & aft body plan of the "Gun Boat No. 1 with Prattville Engines." which is supposed to be the plans of the Huntsville and Tuscaloosa? Decidedly unusual plans - raised bow and stern and very broad beam.
