Yep, it's from
The story is just what it sounds like from the headline: Couple buy a toy soldier, only to be told they cannot take the figurine's three-inch-long weapon on board the plane with them (nor may they stow it in their checked luggage, apparently); they were forced to mail it home to Canada. And even that wasn't without incident.
The whole article is made by this quote from Adam Forty, the Royal Signal Museum's spokesman: "The ‘firearm’ is three inches long and cast out of resin. It’s probably just as well we didn’t sell her a toy tank."
