A very tiny "CBO" in a Lazy N mold, also called the oil can mold.

I've posted pics of these chips previously, but scans are better than cellphone snaps.

No reference in TGT. Anyone have an idea on ID? Any more info on manufacturer? If I was blindfolded, I would swear that these were injection molded chips, but under a glass, there are no signs of injection points. They feel like a soft plastic, but are compression molded and have a ring when dropped.

Thanks for looking!
