I've never been able to find N1337, Irwin. Below is a pic of the 5 different white/grey/beige Aladdin 1's that I know about. I believe the descriptions in TCR need to be rethought. As I've mentioned before, I don't think the red vs. pink colors on the inlays constitute varieties. There are other chip characteristics that distinguish the varieties without need to refer to the color of the Aladdin in the logo.

The beige colored chips on the top row appear to be a custom color for the hotel as there aren't any that match in the Paul-son color set.
