You know, one thought I had was it may have gotten lost in transit in the USA. Someone last year had a HP Twin 1.20 get lost in shipping. It later turned up for sale by someone who had bought it at a USPO lost package auction of all things. That makes one wonder if a postal employee saw what it was and purposely got it damaged and lost, just so their associate to buy it at a auction. The engine was lost in the USA but the USA buyer had  posted it in a Canadian Ebay auction. The original owner managed to get the guy to pull the auction though, but not by choice.

So if it was stolen or something, it may show up on a Ebay auction someplace.
