Whenever I purchase a badge the first thing I do is check it against my private collection to see if it is a new variety. Given the minor detail which could count as a new Die or a different colour shade this is always done under a magnifying glass. 

 After many decades of careful research its safe to say that the vast majority of badge variations have now been catalogued but previously unknown items do occasionally turn up. This recent purchase of a white waistcoat cricketer is one such example and required no magnification because the difference was evident to the naked eye.

As you can see, the backstamp from the maker GAUNT of London was clearly produced in two sizes. It is yet unknown if this variation is present on other badges produced by GAUNT. Closeup below:
