I know this is an old thread, but since this is the best info I've found on these, I'm asking here.
I currently own three of these badges but noticed some slight differences in the lettering and maple leaf. Turns out that I actually have two variants.
I have two of the right one, but only one of the left variant.
The left variant does not appear on any of the photos I can find online, while the right one seems to be exactly the same as all the ones I can find. But both of the ones I have don't have the BMCo markings on them, while the one on the left does have the markings that are described in the first post.
(the center one is the type I've never seen before)
It seems like there were different types, but I'm wondering if both of these were present in CMPs.
