These are the earliest illustrations we have of Agouti cavies and, although we believe that they are of American animals, they are nevertheless still of interest in illustrating the features of winning examples at that early stage of development.

C H Lane's Grey Agouti "Greyfriar"

The "Grey", later known as the "Old Grey", is believed to be the fore-runner of the Silver. This in turn underwent a transformation in the early 1920s when classes were staged for "old" and "new" shades of Silver. The "new" had been developed by Mr H A Sheffield and quickly gained favour as being much superior. Evolution of the Silver continues to this day.

Mr Sheffield's enduring contribution to the variety is immortalised in the H A Sheffield trophy which is awarded for best Silver at the Young Stock Show.
