Don, informatively written. Thanks for sharing.
My thoughts would be the tinnie (day badge) was for the viewing attendee's donation and remembrance, while the enamel pins were for a slightly higher donation (contributors) or possibly event organizers? Since I see no serial numbers. I would think competitors would get a cup or salver. If not a numbered event badge. Judges normally got numbered badges I think.
The plaques (door plaques), a competitors or organizers remembrance purchase option as not being numbered.
This is all conjecture on my part.
I have observed very few examples over the years. First time seeing a plaque.
