Apologies in advance if this is the wrong venue.
In taking care of my grandfathers estate I came across this:


Could this be a Governor General's Prize from the 50's?
I know he won a great many shooting competitions in the late 50's and did qualify for Bisley once.
If it is a Governor General's Prize would anyone know of a site where I could find historical winners?
