W3 and Y3 Radial Engine models

History
An early radial engine was the three-cylinder Anzani, originally built as a W3 configuration, one of which powered Louis Blériot's Blériot XI across the English Channel. Before 1914, Alessandro Anzani had developed radial engines ranging from 3 cylinders (spaced 120° apart) — early enough to have been used on a few French-built examples of the famous Blériot XI from the original Blériot factory.
