Sorry to hear this story and I wish you luck in resolving it. Anyone with as much bluster and combativeness on his website as this guy raises all sorts of red flags for me.

When it comes to gunsmiths, I've used Griffin and Howe (Paul Chapman) or Champlin Arms with good results. The work costs more (but not a lot more) and you are assured of responsiveness and someone who will stand behind the work. Also, the name association helps with the value of the gun.

I know this is not much help in the present situation. Again, wish you the best.
