Mike,
If you want to know about the American Custom Gunmakers Guild, I would suggest you go to their web site and read about them.
http://www.acgg.org/I have shown with the ACGG/FEGA joint show in Reno, NV since yr. 2000
Yes, they are more about the Bolt and Single Shot Rifles, and Shotguns , but they are not ignorant as to quality of workmanship.
This is what Hugh's Rifle was judged on , Quality of Workmanship.
Does the work show "mastery" of the skills necessary for a high quality custom product ?
Hugh's rifle does, without question.
Now I must admit, that there are things about the gun I would have done differently to meet
my sense of artistic balance, but that does not negate the fact that the "piece" is done by a person who has "mastery" of his medium and therefore can be refereed to as a "masters-piece".
Mike, I would say the same for your work also, and a host of others on the ALR forum.
