Dan:
You are absolutely right regarding the six "boxes". They are, I have read - and belive- rafts.
In Mr Østbys book, they are quite clarly shown in several photos in the time before April 9th, although not all six at the same time as the photos are taken from below.
The rafts are also drawn in the color illustrations of Blücher in the same book.
But NO RAFTS in the "final" photo dated April 8th (the one were the turrets are being painted). May be the rafts were taken down as the painting was carried out?Were they ever put back in place? I don't know...
Repositioned to more suitable locations? (just guessing).
Mr Alf R Jacobsen in his book "Krysseren Blücher" states that Blücher were given 10 (not 12) rafts and lots of life wests (still not enough by far) before Weserübung. No position of the rafts is given.
My conclusion:
The "boxes" are most likely rafts. 6 each on B and C-turret. 4 in line across the turrrets from side to side where tha rangefinder boxes are, the other 2 in front of these.
So you can "safely" position rafts up there! I have a lot of surplus Trumperet rafts in my "parts-bin". I tried to put them up there, found them to be a bit "untidy", so I decided NOT to include them in my "9th April Blücher".
To mark the presece of rafts however, I positioned 4 rafts rear of the Signals Platform, a quite likely place for rafts - I think...
The space used to be occupied by small boat(s), later repositioned to new position in special davit - as in my model (and also a nice place for covering the fixing of the wooden deck needed to be carried out as a result of the mods of the Signals Platform itself

).
Boxes for Lifessaving Equipment/Wests: I have (in accordance with photos) positioned 2 such boxes each side, close to the rearmost 20mm AA-guns. Photo show them to be of a different shape to the ones on the turrets,- and probably same boxes as you will find in Dragons Scharnhorst 1943.
Life-Wests in Blücher: According to Mr Jacobsen, these were tied to the railing on both sides of the ships rear superstructure. These, he writes, fell "victim" to the fire that broke loose after the shelling from the shore batteries.
I have not seen any picture proving any of this, but have no indication to prove it wrong either.
Yes: One more thing: Plastic sheets: As thin as possible... ( I used 0.1 mm, but surely you can go up a bit if 0.1 is not available to you).
I always try to remember that everything must be multiplied by 350 => 0.1 mm give as thickness of 3,5 cm - which probably is at least twice the actual thichness of these plates....
