These are pictures of my U-552, Type VIIC, 1/72 scale U-Boat by Revell. I put a resin pressure hull in because I opened up all of the flooding holes and if someone were to look in they would see a hollow hull. Unless you are entering this model in a contest I recommend not putting this in, you can't see any of the details unless you use a flashlight and peer in all the open holes. The open hatch is all scratch-built, and is intended to give the viewer and idea of what it is like. Many of the fine parts were broken in the box, especially the bandstand railing, it was in multiple pieces.
