My first shipment to Anchorage airport, the customs agent there said that my antique guns weren't antique because they didn't meet the criteria of all three of the BATF paragraphs defining "antique guns". I asked him to look at the definitions and of course at the end of the first two paragraphs it says "or" not "and". I pointed this out and he said "I've been doing this for 12 years, I know what I'm doing". I then phoned the BATF and explained what was going on and then handed the phone to the agent. He was very surprised that he'd been doing it wrong for 12 years. No apology though.
