Hmm. The pic I thought was Bismark turns out to be Prinz Eugen, in the USA at the end of the war! Might be the one you mean Paul, where the Arado is either being removed from, or placed on, the catapult.
I've now searched through all my magazines and books, and still can't find the article which I'm convinced I've seen.
But! I've discovered a DVD in the 'World War 2 in Colour' series, which includes Bismark, so I'll have a look at that over the weekend and see if it reveals anything.
