Governor General's Prize

Shamelessly cross-posted from CGN:

Apologies in advance if this is the wrong venue, weapons and ammo seemed the best bet of finding someone that might be in the know.

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?

Recently came across the shooting program for the PEI PRA in 1958





I am surmising that the GG's medal listed above is this one he won in '58, unless he won a GG medal multiple times over the years. Anyone have any idea where I could begin to track it down?

As well from the same program:



Would anyone out there recognize the Snyder trophy, or know if it's still in use?

If so, would it be either of these depicted?
