The chances of there happening to be another falcon kit that had just happened to get the address torn off is also pretty astronomical!

Having said that, unless it was shipped from the same seller (which I'm sure Ady will have made sure is not the case), it's near impossible this guy would have got Ady's Falcon. Unless Ady's falcon's address was torn off too (would be a huge coincidence), and the other guy made a simultaneous claim for his missing falcon, and ended up being handed Ady's £200 model instead of his own by inept Royal Mail staff.
