It has a look like the cnc stock machining process could have gone quicker without as many tooling changes at least to rough out. I wonder if they're milling the wood in steps, though relatively quickly, with the thought to incrementally remove warping with the intention that less warping will remain as they approach machine finish dimensions.

I really can't see that it's too far down the road that a stock is milled off of the scan of an action. I'd think a smith could email a file to a knowledgable shop to machine a blank rather than needing to have the machinery in house. Maybe.
