Curl,
Finding a particular style of figure and color for someone is like trying to buy your wife a dress. You need to do the legwork (keyboard and mousework these days) yourself as nobody else can put their finger on it.

Search for Turkish, French, English gunstock blanks. The usual suspects are Hunterbid.com, Dressels, Luxus, Denli, Oldtreeblanks.com, Cecil Fredi, etc.

I know there are some that will disagree here, but I bet your stock is naturally much much lighter colored, . There is definitely oil that has darkened, probably alkanet root stain, and some dirt, on the wood. My point is, just keep that in mind when looking at woodblanks. Look for structural alignment of grain in critical areas, figure of your taste, then color last.
