I have a S&W 66-4 3" for sale. It is has a matte finish, pinned front sight (which has white paint on it from the previous owner), adjustable rear sight, hammer mounted firing pin, ported barrel and a serial number of CAU00XX. I unfortunately do not have the box.
It is in good condition but does show some marks on the matte finish (nothing severe).
