Thanks John. There are several instances that I am sure you are aware of where UK casinos used chips or jetons with the owning group on them rather than the actual club or casino name, so this does suggest that they are UK jetons used in a casino.

I just can't believe that I have had these for a few years and never noticed until today! Makes me think I need to go and check through the box of chips that I have with extras from when I have bought other sets of chips over the years.
