In many ways the makers were more jewelers than much else. I have seen only a few pieces of deBoutet's work but like it or not, (and I do), it is impressive. I also know that there is at least one set of his pistols that are spurious, made by a very talented fellow who passed away many decades ago. France has declared any guns that deBoutet made are national treasures and cannot be taken pout of France. I actually thought that the pieces that recently sold would fetch more at auction than they did. Since I haven't won the lottery in the last 84 years, I wasn't bidding on them though.
