Hi ART I found this story from a broadcast that was aired on PBS, it was a short documentry kinda instresting but yes they said it was floating up around the coast of Louisiana Im 43 years old and do take an instrest in history,as far as I know the sub is not on display any where,its still sitting,in some where house,in the tv documentry they went to some archive,and found a picture of a man,in a confederate uniform, next to the sub,He must have helped build it they said he was a machinist the type of person who would be skilled enough to build such a type of sub,they gave a name ,but I would have to replay the documentry that I video taped to find the name of the person who helped build the sub,its very instresting,they did find old cival war records of this machinist,
