How did you finish the walnut? Even lacking in shine it has a nice rich color.
If you look closely you can see more than one color of stain over the already redish brown walnut. The exact method varies from one stock to the next and requires experimentation. Still to go after everything cures is a clear sealer to add durability but very little shine. The colors found here are orange gold red brown and black.
If you do it right you can nearly match almost any original color found on antique guns. The color layering technique I learned from Jack Duprey and Jimmy Kline. I would prefer to start a different topic rather than go into detail here.
