It has been about fifteen years since I saw it, but there was a very well done model of a Gato type boat in a seafood resturant in Oakland California. The model was about ten feet long, and had been used in the movie "Run Silent, Run Deep". I was never able to find out too much more about it, and don't even remember the name of the resturant. The model was very well done, however, and the bartender said that it was a fully running boat.
