This is one of the original miniatures (or more appropriately, props) from the Voyage to the Bottom of the Sea movie and later TV series. It is mainly seen as a model in Admiral Nelson's office. Its proportions and lines are different from the larger 8 and 17 1/2 foot miniatures used in the movie and TV show and it is thought to have been the basis for the Aurora model kit.
