I think it is fair to say we see Best quality work from vastly different viewpoints. I re-lay ribs routinely as part of daily shop life. Do I enjoy it? No, not really. Do I see them as something of an abomination? Hardly. Something always looks "off" on those Alex Martin guns. The Boss O/U? Best work by anyone's book. Vastly different guns and designs. Holland and Purdey both figured it out long ago. As to why prices have not come down, well that is pretty straight forward. Watch the video that Holland put out and see the factory. The overhead is huge! The machines cost tens if not hundreds of thousands of dollars/pounds. The number of hours it takes has not come down that much and labor is much more costly than in the past.
The news ways give us repeatability, and efficiency, but they do not remove the hours or overhead required to put out a product of this nature. It still takes time, and lots and lots of skill.
