Ten grand to spend on a new-production rifle?
When I was a kid, I had access to a Nicholas Beyer rifle that is one of my favorite rifles. I'd spend some of the money to locate and document or borrow that rifle to use as a basis for the build, but as the rifle was new rather than in the current condition.
If working from a kit, I'd go with one of Mr. Klein's Beck kits and have him do the work. If from scratch, I'd contact Louie Parker, Dan Phariss, or Dave Rase.
