Found these pics on a disc today. I did this model of Bushnell's "Turtle" as a comission many years ago. The Turtle was the first American submersible developed by the American inventor David Bushnell in 1775 for use against British warships. The pear-shaped vessel, made of oak reinforced with iron bands, measured about 2.3 m (7.5 feet) long by 1.8 m (6 feet) wide. It was equipped with a mine that was to be attached to the hull of an enemy ship. In 1776, in New York harbor, the Turtle tried to sink the British warship HMS Eagle but failed; none of its succeeding missions was successful. Neat little model that came out pretty well!
