The ESP Guitar Company

Looking for some advice about this guitar. There are a few things this doesnt have that I've seen on other SA-2s - no ESP logo on tuners, no cutouts on the back cover that cover the springs, no esp text on the pickups and the serial number - doesn't seem to match with normal convention with ESP serial numbers. SJ0800848. I have seen pictures of others that match the things I've mentioned previously including SJ... serial number. Have also seen one that starts in L. The guitar itself plays well, the Floyd works perfectly, guitar has good weight to it, would almost consider it heavy. Any thoughts? Thanks in advance.
