I see the seller isn't too popular with some members . Sad though to see this happen to a pin - to me this is a timeless theme, cool (simple) art & colours, one piece of pin history. I'd love just one EM in my small collection, it doesn't need to win any prizes for best EM game or condition. Sounds like this one's way way beyond help though - how does a pin lose it's head & legs anyway?
"Container Filler".
More than likely, this game was throw in for (as it is - missing parts) free to fill the container. Common from the supplier in Germany (well it was common years ago). Basically, the game was a freebie.
