I think actual seconds have become less produced, I surmise. I think what is more common are economic lines of pipes from manufacturers. Savenelli has the Rossi line. Nording has low end Nordings, but also used to have Eriksen, which were great little factory pipes and durable. At least in new pipes, I don't count Parker or Britannia as seconds, more low priced lines from the Dunhill factory, and noticeably good pipes. But I wouldn't bicker with the idea of seconds. A few pipes really do wash out of the expensive lines and still get sold, like Savenelli's unfinished pipes. House pipes aren't seconds, per se, but are often a way to get pipes by mainline manufacturers at a lower price, with the fundamentals done well, if not the same level of finish.
