So far, Spectre, only 'smith-types I've seen lurking around here are pistolsmiths. Would be real interested to see if anyone responds to your query...or if anyone has any KNOWN AND RESPONSIBLE referrals for you.
Frankly, my shop is always looking for decent rifle and shotgun 'smiths to whom we can refer work. Good luck on your quest...if anyone worth a hoot pops up, please let us all know if he does so privately.
