If he's still available, try Harry Lawson at 3328 N Richey Blvd., 326-1117. He's the fellow that first designed, and probably still manufactures, the rifle stock with the thumbhole grips.
I met with him in the mid 90's to see if he'd be interested in the gunstock carving I was doing. Although he didn't use my skills, he was very encouraging and even invited me into his main office where he had a gazillion mounted trophy's from the many hunts he's been on. He shared his big photo album with me and gave me a tour of his workshop where his duplicating machine made replicas of his special stocks. His name was/is very well known, and it made me feel sort of 'recognized' as a fellow-woodworker. He probably wouldn't remember me...
Anyways, I thought he was kind of 'up in years' at the time and wasn't sure he was still around/in business. Wouldn't hurt to give him a call...if he can't help you himself, perhaps he can give you good direction.
