This puzzle came to me from ebay via a friend in the US. The seller took it apart to ship, but unfortunately they forgot to put one piece in. Then one of the pieces got mixed up with the packaging. So I thought that I was going to get 12 pieces instead of the 14 it should be. Thankfully the seller shipped the missing part and the last piece was discovered, making me a happy chap again.
It is one of the kumiki puzzles that can be used as a money box, the slot can just be seen under the roof of the box.
Looking up on the internet I think this is called a "Norimono" in Japan - does anyone know for sure? I can see the characters for Kumiki on the label, but the rest is lost on me.
