I read the write up on pachinko planet but couldn't find any of the criteria mentioned in the article. There are some raised numbers over the upper right plate (5507). None of the other plates seem to have any numbers on it. Here is a picture of the machine. Let me know if any close up's or picture of the back of the machine would help identifying it. Also not sure why the picture is appearing side ways on my computer it is in the correct orientation.
