This is still in production, it can be found "new" but this is a prototype for the new one. ESP makes the samples to test out various colors, finishes and to show to dealers prior to the actual model being built. They take them to shows like NAMM and start taking preorders for the new years model. Some Samples are never make it into production models.

You can see the plate on the back where the neck meets the body looks to be spray painted. They are normally also stamped with "ESP"
