I just picked up a left handed 4 string spoiler,and cant find any numbers on it.I would like to find out all I can about this bass,as it is my first Alembic

Jack,
  As far as I know, the serial number is in one of three places: on the peghead, on the truss rod cover, or on the fretboard at the 24th fret. Also, check the electronics cavity if all else fails...
