Supermarine Sheldrake

The Supermarine Sheldrake was a British amphibian biplane flying boat developed by Supermarine from the Supermarine Seagull with a revised hull. Powered by a Napier Lion engine strut mounted above the fuselage and below the top wing, it was fitted with a four-bladed propeller. Only one Sheldrake, serial number N180, was built.
