and I got a "Why not" on my questions if this could be from that casino upon asking some of the experts here in Europe.
Is it 100%? No, as I read here most of the times we can only be 100% sure when we find other pieces with the casino name on it.

Even some very nice MOP examples are still a mystery. This should NOT keep you from searching and enjoying it all.
Like these two, still waiting and hoping to find out more. Enjoy your MOP collection, I do.
