yes, agreed! And that makes a nice descriptor for the differences between those two variants of plate then. Mick's point is very good. What will perhaps happen is you will get a list of x with each of those having y variants... and then the forensic case will build up for which are definitely original and which reproduction amongst all found.
Will be interesting to hear the differences in profile in the two plates Henry has i.e. is is down to the amount of acid exposure, or could one be a different process?
