Also, noting Walt's subject line, while a Confederate "tar" reenactor could perhaps have a copy in his possession, these were for ship-to-ship (or CSN reader to CSN reader). The "brown water" CSN's ship/shore signals were taken care of by posted army men
using the Myer-Alexander system. In the case of the "James River Flotilla" (see Dr. John Costi's book) this assignment went to the adjacent Independent Signal Corps of Cap./Major Milligan, who delegated the task to Cpl (later Sgt) F.A.G. Handy, with one or two men per unit afloat. Evidently similar case in Charleston waters, with ship/shore an army task (following Union precedent?).
