Thanks, John. I should have looked there first. I do see the crest and seal pictured. However, there's also a series with a mold that Kregg has identified as crest and seal but obviously is not. They have inlays and the mold looks like it might be HUB.

I'd still like to hear more about what went on in these Mexican casinos in the early years though. Were they relatively honest or out to take the gringos? Did they have the table games we see today in Nevada or were there odd games that don't exist anymore?
