I think Jay has the outer ring for this so if it could be superimposed we could at least get a good idea of what they looked like.

I do have pictures of 4 ABP Myers chips that show the outer rings (with ABP Myers centres) but not possible to show them on here, I'm sorry to say.
Orange, Turquoise, Black and Pink and all impressive.

The card ones are quite large, I think there were 3 (at least) but they are long gone now.
If anybody from the guide wishes to add these then please feel free.
