The A.104 was a slightly enlarged version of the A.103, and added a second seat beside the pilot's seat. The cockpit was enclosed by a perspex bubble with the engine at the rear and the tail rotor carried on an enclosed boom.

Two piston-engined prototypes were built, followed by a single example of a turbine-engined variant designated A.104BT. No production resulted.

An example of the A.104 is preserved in the Museo Agusta which is maintained by the Agusta company and is located just south of Milan Malpensa Airport.^[1]
