The plane in the photo is obviously a piston Convair, but looking in the FAA aircraft registration database doesn't necessarily tell you whether a plane is a 580, a 580 will still be registered as a CV340, or CV440. For aircraft certification purposes, a 580 isn't an aircraft type, it's an STC modification.
