Sorry, can't help, but I noticed something odd. Canning suffered from a receding hair line and, like many men, compensated with slightly ludicrous hair growth elsewhere on the head, i.c. horizontal sideburns running from his ear to halfway his mouth. The sideburns are gone on this portrait. The hair is also curlier and the nose is of a different profile than what you see in other portraits, but that may just be artistic liberty
Based on this really slight evidence, I wonder if maybe this medal was made when Canning was starting to fade from public memory, later than 1927, perhaps even later than 1930, for some kind of commemoration?
