Thank you Zac, I learn something new. Interesting!

I don't see why this is listed under Scotland rather than Great Britain. Brunk lists it under Great Britain, and rightly so. He lists three 8 reales with this countermark, dated 1790, 1793, 1794.
Most such countermarks which are limited to initials cannot be traced back to the originator. There are simply too many possibilities. In this case, however, this is a high quality countermark on a high denomination coin, so this should narrow down the possibilities. It was certainly produced at the time of the great silver shortage in the UK.
Again, this (and some other countermarked coins) should be moved from Scotland to Great Britain.
Not a single occasion though. Mexican silver coins were popular in XVIII-XIX in maritime countries who were short of their own silver. For example, in Canada mexican pesos were punched in the middle to make two coins out of one; the middle part served as a smaller coin, and the larger part (with a hole) as a bigger one.

Agreed, 1793 was almost a century after the Acts of Union... it would be like having the George VI and Elizabeth II Scottish design shillings in Scotland instead of in the UK.
On this occasion, I am inclined to agree since Krause & Mischler list similar pieces in their Standard Catalog, not the Unusual World Coins edition, in a section after the regular circulation issues under the heading 'COUNTERMARKED COINAGE - English Tradesmen'. Whilst this specific type with a Mexico 8 Reales as the host is not listed, they do list this same countermark on a Lima 8R (KM#A645) and a different crowned '&' countermark on Spanish Colonial 8 Reales (KM#645). The only possible worry we might have about this particular Mexico host with the 'CBCo' countermark is Krause's last comment, "False punches have been used on genuine host coins."
