The ESP Guitar Company

Hey new here ...well sorta i use to post around here around 2005..anywase i acquired this 80s ESP 400 series strat (ST465) ?? . Looks to be 2nd run Black ESP logo Blank bridge saddles 22 frets..i know the pickguard is not original and strap button on horn is slightly repositioned but my question is this body original.. What got me thinking there might be a slim chance its not is the gap in the neck pocket (is this there for easier t rod adjustment  because off the 22nd fret hangover ?) and Painted neck pocket ... I saw another esp 400 body pic it didnt have the gap and the neck pocket was un painted (maybe that was a 1st run model with 21 frets esp logo saddles)
