Oh, I forgot to comment on the pressure hull!
If you remember, there is no aftermarket full pressure hull for the Type VII. The one out there is only a partial one . And in my opinon, is only good if you are planning a waterline model. It is not complete as far as all the open vents, inlets and drains for a full hulled model, and it is not accurate. If you want a proper pressure hull, you will need to scratch build one. I am sure Revell of Germany will not go to the extra expense of putting even a partial one in their new Type IX! I am wonderfully suprised that they are even coming out with this the model of the Type IX given all the expense of research and making molds for this very large new kit!
Just my opinon understand, I have only been building models for 50 years!
