Posting here is a good start.
Casino Rarities had one but I just checked and it's been sold.
Two recently auctioned on ebay which I happened to be the lucky winner of one.

On the other the reserve wasn't met:

You may want to contact the seller to find out if he will relist or offer a price.

Good Luck !!
