Re: 1991 Strat...
It looks to be an American Standard , that is not a Deluxe. It was made in 1991-1992 in Corona CA , The neck is Maple and that is a Walnut skunk stripe on it , fretboard is Rosewood. Body is most likely Alder or Ash looks to be in decent shape , people pay anywhere from $400 to $800 for the most part. Also looks like it is original condition , a good gift for your brother that is a nice piece ,nothing wrong with it at all.
