Yeah, Transmaster, it was an NTIS librarian lady that I was corresponding with back in the early eighties. I had already been ordering from them. Given that it was a new publication at that time I figured that it would be hard to obtain. Also, after a period of time and no manuals arriving, I began to think that there was maybe some hanky panky going on, especially after I received the bill for $250. But they are beautiful, fresh, original manuals which I still have and are worth it to me. Covers are heavy blue colored plastic. By the way, if memory serves, those destroyers were built in a Mississippi shipyard.
