This model (with the bird inlays) was only offered for 2 years, 2006 and 2007. This is a 2006 as it has the black hardware. Has a bit of a smudge on the back, ill try to polish it off. 

It is a sample/preproduction guitar. 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.
