That is what is called a "Holy Grail" pipe. That is a pipe that was made in limited numbers for a short period of time. It's unlikely that it's still in inventory anywhere so the only real possibility is to find one is on the estate market. Ebay will give you access to the most estate pipes but retailers like Pipes & Cigars, Smoking Pipes and others also have a sizable selection of estate pipes. Click on the sponsors links and brows through their estate pipes. Sooner of later one will surface.
