The difference is that this is made by Supermarine - it's a bit like saying today's Triumph Motorcycles are not real Triumphs because they are built in a factory in Hinckley (which is reputedly the best in the world) rather than built in Meriden (which by the time the Unions finished with it was the worst in the world). Or the new Mini, or the new VW Beetle, or the new Fiat 500, or the X-Type Jag, or the Landrover Defender, or the new Range Rover, etc...
