Submarine "BEA," religious, un-built, undated

This reproduction of the section and elevation drawing differs slightly from the original drawing on vellum that is in Flat File 227 Folder 2:  http://digital.lib.calpoly.edu/rekl-4980 (the bird on the top of the body of the submarine has one head, the original drawing has two, and the second head possibly was added after the reproduction was made?).
