The blanks were mostly pre-turned by an outside wood monger, before they were delivered at the factory. Anything really special came in as a dry, unturned blank. The LOP was trimmed to be a little long, and the turned stock was fixtured in a lathe at the correct angle, and a two step drill did the hole at the precise angle.
I had a custom stock fitted to my R10, Herve roughed it down to about what the pre-turned stocks looked like, taking big, scary cuts with a spoke sheave, was duck soup to him. Then it was drilled, bolted to the gun, and about two hours later, unbolted and off to the checkering studio.
The problem with stockwork, even in France, is getting the hole right. Youve got one try.
If you can get the hole right, at the beginning, I suspect a Darne might be a very easy gun to restock. That is the only gun Ive ever seen being restocked, and I have no frame of reference, but, it went quick on my gun.
Best,
Ted
