Thanks for the offer, Draka! I think, I'm pretty good set-up for that, also using the actual crew names etc. Except, after the second war patrol, activating the "Random crew change" in the Sh3_Cmdr, as the actual U 45 was lost on 14 Oct 1939.
As for the survival of U 45 in the current WAW VII campaign, I guess, I'm trying to re-write the history books
I suppose, you'll just have to stay posted to find out ...
