The casino was named "The Playboy Club" in London.

At this point we know there are two 41mm examples, a 31mm example and a reported (no image) of another color which is fact. All are solid colors and others are with color edge graphics as seen down the index.

All resemble non-denominated Roulettes as seen in Portsmouth.

Not possible to say I am sure since there is no info, thus all my questions and responses from others in all archived posts and posts today, that they are Roulettrs.
