These guys (Great American Gunstocks) have a lot of the older patterns and have a good reputation...

BTW, even their "Bargin Bin" stuff is very nice stuff...I go to their web site from time to time just to drool...

As for someone doing that actual work...that's open to a lot of debate, and the list is dwindling fast. Classic stock work is a dying art (unfortunately)...
