Just glancing at the pictures real quick there are a couple things that pop out. Most likely it is an 02, the 03s have the LEDs in the back by the switch. The side mounted LED was a conversion, I think done by Dan Voils, and it should have MAC noids. The clear cover on the side might mean a Tadao board inside, which is good for resale, and is easy to check. Shame the sidewinder got swapped out but the gun will shoot so nice no one will care.
