Unfortunately for you the word 'Antique' differs in the U.K. With breech loading rifles and shotguns they must be pre 1939 and in what is classed as an obsolete calibre. All muzzle loaders made prior to 1939 and pistols pre 1918 and in an obsolete calibre. The British Home Office publish a list of obsolete calibres which I think is somewhere online. All shotguns and rifles, regardless of vintage, if in a current calibre do not have antique status. So, a 12 bore made in 1863 is not an antique but a 24 bore made in 1938 is. In other words you could buy an antique shotgun here in the U.K. without restriction and fall foul of the law when you got it back to the U.S. where it is not an antique. So, not just two countries divided by a common language but by odd laws as well. Lagopus.....
