I'm putting together and have been for about three years a database of all British built conventional submarine. The info I am amassing is class details techy stuff as well as all the stuff and more if I can get it that Janes supplies laid down, launch and completion dates,yard numbers etc, fates, events and fate dates and COs. OK I have got a bloody great base but I still have info missing. I have a mountain of books and a few contacts but still yearn for more. If anyone knows of any good books contacts or has info they wish to part with or share info with me that also would be appreciated. I am looking for info on the later classes and some very early types like the H class etc. Post WWII info skippers and techy stuff. What yer got? Please My intention is to put this into book form and get it published.
