Revell 1/72 German Sub VIIC Wolf Pack detail

My solution to this problem was to purchase a second kit and build it as a closed hull model. I placed both boats on the same stand with the cutaway lower then the full hull. The cutaway contained all four CMK interior kits (torpedo, command, cpo and engine rooms), the Yankee Modelworks pressure hull, White Ensign Models torpedo loading kit, 50 figures from CMK and Revell on and in the boat. I also cut away the deck to reveal the pressure hull. On the closed hull boat I placed 15 CMK and Revell figures as though the boat was in a surface gun action. The deck is from Nautilus models and I used drawing inks (50% black and 50% white) to stain the wood. Both ships have some Yankee Model Works PE set parts plus scratch built additions.

I would not recommend placing the pressure hull and interior kits on the same boat as the kits are not compatiable and I wound up cutting about 80% of the pressure hull off to make it fit with the other kits.

 The whole purpose of the internal sections is to make the sub a cut out model as far as I know. 

I am not sure if you want to be able to open and close the sections to show what it looks like from the outside then removing the cut outs to reveal the insides. As I am sure you are not intending on building the internal sections and then closing the sub up so as to never see the internat section again.

 It is possible to make the sections replacable, however I am sure that would be a heck of allot of work. 

 My suggestion would be to only cut away one side of the sub, as most people I think do, and when you want to show the model without the cut outs just turn it around to the other side. 

I have all the detail sets but have not started cutting out the hull sections yet, just bored out the vent holes on the one kit before I switched over to work on the VII-C/41. I was going to simply discard the removed hull sections but I suppose if one were to first sand down the inside areas of the hull than cleanly cut out the sections with a fresh x-acto blade so to remove the sections in one piece, it might fit over the detail parts.
