I'd send it to Mark Larson...
I just don't understand this... I thought that this is a Do It Yourself Gunsmithing forum... not a referral service for professionals.
I didn't comment on a repair method earlier because I thought that Ernie (Damascus) covered it best, and covered it completely with all pertinent details. So I also don't understand why anyone else suggested cutting out the charred section and gluing in a veneer of walnut, then dressing it down, checkering, staining, etc., after he had done such a great job.
Ernie nailed it on this one, and his method should be very sound and nearly undetectable if done carefully.
