Mike's gun certainly falls in the category of 'Non-standard work', a term coined in a post higher up.
If we take the 'Isaac Haines' rifle design as counterpoint, everyone is so familiar with it that there is almost a 'standard' to which a gun must be built, colored and engraved. It does not mean the guns aren't beautiful. But popular trends can can lead to stagnation in the contemporary arena.
There are such benefits to the WWWeb, examples might be research of original work, exposure for one's own work, and exposure to others' work. But a benefit can turn to a downside where a FAD takes on a life of its own, a certain school of rifle that EVERYONE starts as soon as one really cool work shows up. Then this fad rifle gets to be boring, overused, and eventually, unappreciated, almost no matter how good it is. There really isn't any cure for this disease. I had gotten the bug many times myself!
Mike's example gun, and Ken Gahagan's Club-Butt Fowlers, are reaching beyond this 'comfort zone' of the contemporary American gun. Hurrah! Fun stuff to see, and inspiring.
