I have a Weber bulldog. Good pipe. I read Mr. Weber's book. Looks like your Shellbrooke is one of Weber's lower range. Yours does have a strange appeal--I say strange because I normally don't like carving on a standard shape. (Pic from Pipedia.org, courtesy of Doug Valitchka.)

That Shellbrook ad claims it was a “hand carved masterpiece”, which might mean they were machine cut, then hand rusticated after a smooth finish was obtained on the pipe.
Yet the ad claims it had an “aluminum screw stem fitting” and mine is definitely a push stem.
How did they mask off the brown raised parts and stain the rusticated parts? Or, could they have rusticated and stained the entire stummel then polished the raised parts a shiny brown?
There was some hand work, for sure.
