Guns that passed testing were stamped with a mark representing the proof house. The London Gunmakers Company set up a 'proof house' in London, and not surprisingly… firearms makers who were not part of a guild tended to fail testing more often than the guild members.
In 1637, after heavy lobbying from the London Gunmakers Company, a London-area firearms guild, King Charles I issued a Royal Charter setting firearms safety standards. The first proof marks started appearing in 15th century France, and by the 17th century, European firearms guildsmen were heavily promoting their use - and lobbying their governments for laws requiring them - primarily to dissuade competition from non-guildsmen and scare potential purchasers away from un-proofed guns. But like many government regulations, their origins have more to do with self-interest than safety. In modern years, they truly do serve that purpose. Proof marks are stamps embedded in certain parts of a firearm following (and sometimes during, depending on the firearm type) its manufacturing to indicate that the firearm has been 'proven' to be able to handle the specific type of ammunition for which it was designed. And even if you're already familiar with proof marks, maybe this article can broaden your knowledge and teach you something new.
