So I got my brother to list the said "Vintage Fireman's Axe" on facebook trader, thinking that they may have more "relaxed rules", but the listing was taken down off facebook trader within a few hours. The reason given, apparently, was that a "Fireman's Axe" could be a potential "weapon". Presumably there are cases of crimes being committed by criminals wielding vintage fireman's axes but I can't say that I've ever heard of any.
