Recently, I had a barrel and a stock for a pinfire made in 1865 that
a well known gun maker in England couldn't send me. Royal Mail
wouldn't touch it. Had an experience with US Customs in Sacramento.
They wanted proof it was an antique. As it was a percussion gun, no
proof should have been necessary. Always assume that Customs agents
don't understand US firearms law - and you will never be wrong.
