I have some remote inkling that they were marketed in association with the automobile brand. If that's true, the question is, who made them? As with house pipes at pipe retailers, sometimes this is difficult to ascertain to preserve the identity with the retailer. But since it was Bentley, I assume it would be an upscale (very upscale) pipe maker. I'm fascinated (being an ancient car buff) that you immediately associate the Bentley automobile with rap! I guess it's true that rap artists are a concentration of high earners who can actually afford the cars, but I didn't know they had so identified with the brand. I wonder how hedge fund managers and oil men feel about that. The brand has an interesting history; I think Bentley split off from its mother company Rolls Royce and is now, maybe, German owned. You see them (Bentleys) tooling around Manhattan, and the thought of driving a car that costs as much as a house through Manhattan traffic gives me pause. Maybe a Ford Focus ... or something.
