My reason for asking:

At ChipGuide; CUBA, under "UFO's unknown Casinos, there's monogrammed "HCM" CG082792 and CG082793...

...and at URUGUAY, I see the "HCM" monogrammed chip CG078937 [Hoteles & Casinos Municipales]...

...and I got from Maria, who lives in Montevideo; and handed to me in Loxahatchee, the "HCM" monogrammed chip in Mother-of-Pearl.

Did this HCM group operate in CUBA as well...?
