There are some incredible builders here on ALR. Many, if not most, specialize in building in the styles and schools of 18th and some 19th century original and very well known gunsmiths. I consider to do a good/great job of emulating original work a talent almost beyond belief. Like I said, there are builders of that quality right here on ALR. These builders are a wonderful resource to learn from.
Me? I have no such talent or desire. My many years of doing restoration work on many Southern guns for a KRA collector in Charlotte, NC, inspired me to develop my own style, which came mainly from the influence of the restoration guns. I am not good enough to copy the work of anyone, so I stay with what I do and pretty much nothing else.
With all this said I, personally, like mixed metals on a gun. I will occasionally do this on my guns, although not as much as I probably should. It speaks "utilitarianism" to me....using what you have, which was a way of life on the frontier..... or maybe mixed metals could be considered an attempt to "not copy", if you will, the work of others. "Farmer guns" and "blacksmith guns" are 2 schools of gun making rarely acknowledged. Not the high art type for sure but still charming and very real in their own way.
Composite guns have always been interesting to me.....guns fabricated from several damaged guns that were salvaged for parts. I plan to do more of these in the future. These are a perfect opportunity for mixed metals and the creation of a "one of a kind" gun..
To me a good gun is all about the lines, the balance and the comfort to hold and shoot.
Plain or fancy matters not to me. I'm a Southern style maker building my own style. Somebody once said, "in the South we can get away with just about anything". There is probably some truth to that but good judgement is always a plus.
