I would guess that for Bismarck, you can probably get the German 11" OP range (340 range) guns, Bayern 15", classic Bismarck 15", and maybe a super 15".

BTW, I finally got the Deustchland (1935), and got the OP 11" guns. 340 range, 11 second reload. Basically murders everything. Although the Derpland is pretty slow, at 23 knots max displacement. Fortunately, I removed some armor, and got 26 knots.
