It really is a shame that someone would go to all that work to capture all that fantastic detail and leave out one of the most important details---the paint.
It is one thing to build a fancy brass mounted gun with fancy figured wood for a desk top decoration. But to leave this wood in raw blond color is flat, even a dark oak stain would have been better. The blond yellow offers no contrast with the bronze barrel and the whole thing comes across as washed out and bland.
There is a time and place for this treatment and especially if you have some finely figured contrasting wood. This wood might work with a black iron barrel, but it doesn't work with bronze. The wood color washes out the bronze and the bronze washes the blond wood. One does not complement the other.
