The original pickups are included and have been swapped out for a set of Lindy Fralin Big Singles 43 seen in the photos. There is a number 054 on the bottom of the fret board.
Thank you for sending these photographs. Unfortunately we do not have complete records of instruments produced before 2005, so we do not have detailed information to supply. This does appear to be a legitimate ESP custom order produced between 1997 and 2000. We do not have specifications available, but it is likely a solid maple top with a mahogany body and neck based on its design. I hope that this limited information is helpful, and please let me know if you have any further questions.
