This is the full-hull option kit.I built that as my second commision including a base and a case which i experiment with adding brass strips on the edges for a more glamorous effect and also to enhance rigity of the structure as well. The kit itself is very good and is up to the modeller to add as many extras he likes or to go the clean-cut way. I used GMM ijn set for raillings plus all the other usual details such as catapults cranes ,etc.
