We know the MOP chips are from Trouville... and we know the blue/natural bicolor 100 and 20 were brought to our attention years ago as being known to com from Cuba, without any other information which, we can presume the CE bone chip was part of whatever was used in Cuba but, the bone CE listed in Trouville does not match any of the MOP chips from Trouville or the bone chip listed as Cuba.

I think further study and notations would be in order.
