At the risk of beating a dead horse, let me try and explain yet again.
1. Blue Ribands were never made. They were selected from frased stummels in a sorting process after they had been made. They were selected according to qualitative criteria, principally that they had a straight, vertical grain orientation with good to outstanding grain. Adler said that the pipes were always "straight-grained or very good flame-grain." (from the interview transcript) It was the full-time job of those who sorted to determine which stummels went to which factories. Different lines were done in different factories. "Better bowls get put to one side. Certain workmen got the highest quality bowls. Bowls were turned in different factories than finishing."
2. The stummels were then shipped to the Rosebery "top-quality finishing shop" (quote: Adler interview) for finishing and stemming. Blue Ribands were given a contrast stain.
3. After having been inspected AGAIN for finish quality, they were stamped, post-finish, put in a Blue Riband sock and box, and then shipped. Adler said that the reason they were inspected after finishing is that the sanding and finishing process often surfaced flaws which would cause the pipes to be rejected. Final inspection was done by the Rosebery plant supervisor. That's how seriously Comoy took this process.
These pipes were in very high demand by collectors. Adler told me they could never produce enough of them, and that over time, declining briar quality forced the elimination of the line. Can you imagine the upset Comoy's factory and/or reps (and dealers) would encounter were they to ship out a Blue Riband with the wrong grain orientation, not to mention low-quality grain orientation? The people who bought these pipes knew what they were buying. Comoy didn't play games like that. It is one thing to have a low quality vertically-oriented grain pipe slip through. It is altogether something different to have a poor quality cross grain be selected in the sorting process. It simply won't happen, especially given the secondary, post-finish inspection.
Adler spoke about how important it was to Comoy to "retain high-quality, skilled people in the places they were." The best toolmakers were at Aldershot. The best finishers were at Rosebery.
Could someone have stamped the pipe with a Blue Riband stamp? It is possible. We know that this happened at the Dunhill factory and that Bill Ashton-Taylor actually counterfeited Dunhills. Stamping a pipe does not make it something it is not when that action contravenes Comoy policy. And, as Adler explained, there were fool-proof policies in place to ensure quality.
Finally, these were small companies. John Adler was not some elevated, removed executive with no knowledge of production. He could name the brands, and types of machines used on the factory floors, the processes, all of it. To suggest otherwise it pure balderdash.
You can put a Corvette badge on a Camaro, but that doesn't make it a Corvette.
