Hi Siara,
I understand your comments as regards the Conning tower ring, but, you just can't see it. I did a dry run to see just how much i could get away with, the answer was quite alot! Unless i was going to make the decks removable i could see no point in the extra work.
I also know that you are probably itching to see pix of U-69 with the paint on (as i am yours) so i took some photo's, all of which are out of focus
So here is one of the 'better' ones until i take some more.

Ps I used Revell's deck as a mask as seen here
