In England a gun that fails reproof will have all it's original marks obliterated. The ones I have seen are just stamped over with a bunch of straight lines. So marked the gun cannot be sold--or not as a firearm. Other variations--I saw a Westley drop lock sold this week on Gunbroker that in reproof the "choke" had been stamped over but the gun passed reproof. Must have been honed to cylinder.
