1920 - 1921
This sports car was made by Noel Campbell Macklin after he had ended his connection with Eric-Campbell. It used a 1498cc Coventry Simplex engine, rebuilt and lightened by Macklin's staff, with 3- or 4-speed gearbox and a 2-seater body. Some were very sporting in appearance, with pointed tail and a long external exhaust pipe, though at least one had a more sober 2-seater body with doors and a vertical windscreen. The Silver Hawks and prototypes of the Invicta were assembled in the garage attached to Macklin's private house. Not more than 12 Silver Hawkes were made.
