Harry Lawson Rifle Company. He's the first in the business of thumbholes, and the best. A few have copied his design to some extent, but they haven't got it right. Talk to his son Randy. Harry passed on about a year ago and will truely be missed in the industry, but his son as extremely knowledgable and can help you out. I would imagine that Harry had more patterns than anybody in the business, and he made and designed his own duplicator, which will put the Don Allen's model to shame. Here's his number:
1-520-326-1117.

Tell him I said hello

I second the Harry Lawson recommendation. Randy's done several stocks for me in the past and all were first rate.

If you're looking for a composite stock, Lone Wolf Riflestocks may be able to help you. I had them build a LH Summit style stock for my A-Bolt last year and have been very pleased with the results. http://www.lonewolfriflestocks.com/
