I think G is not a grade of Greeners, but a symbol as to the action type. The grade in that period would be a number which was actually the price. A G70 would be an Imperial , with G the action type , and 70 guinea gun. A G60 would be a Royal, with the G type action, and a 60 guinea gun. Later , as the prices went up over the years, the number of the grades went up.
