Jerry, we went through all this before. I sold a Webley Mk II 455 revolver to a friend, because of its age and a non-readily available source of ammunition, we had to get a certificate from the Firearms Office declaring it an antique and not subject to registration. If your customer did not have such a certificate he could not have imported the gun legally. We do not have the pre 1898 antique status for any gun for which ammunition is readily available. An 1873 Colt revolver in 45 Colt is subject to registration. Maybe one in 41 Colt is not as shells are not readily available.
