Perlas Sub

This sub was found on San Elmo Island in the Perlas Islands. It is a Civil War era sub invented by Julius Kroehl in 1865 and brought down to Panama in 1867 for pearl diving. This was recovered by James Delgado of the Vancouver Maritime museum. Mr. Delgado found plans for the "Sub Marine Explore" in a 1902 article of the history of U.S. submarine development in the JOURNAL OF THE AMERICAN SOCIETY OF NAVAL ENGINEERS.
