This kit is definitely old hat now, with the new Revell 1/72 U Boats on the market. Those are state of the art kits and far superior. Still, I've built the other two cutaway subs (the Type XXI U Boat and the USS Andrew Jackson) so I wanted to add this one to my collection.
It is basically accurate for a type VIIB U Boat. However, the interior seems to cover mostly the starboard side of the boat and omits a lot of interesting areas like the captain's cabin, the galley, and the wardroom.
It's an old tooling, and there are lots of pin marks, sink holes, and flash.But it's still a fun kit to build.
