It is interesting that you ask about the ORCA. I am also building an ORCA.
I have a little different take on it than others. Since I don't want to build the
ship as it appeared in the films, I am building a version of how I believe that boat would havelooked new.
Ihave seen many pictures of the boat from the movies and apparently the movie maker made changes from scene to scene.
I will include of picture of the model in the near future.
I would be intersted in communcating with you further about it.
