Beaker marks help please
Posted: Wed Mar 12, 2008 7:38 am
I would be grateful if anyone could help with the following mark.
This is one of a set of 6 small cups measuring approx 1.5" high, the mark appears to be in the shape of an island with the letters A & D in 2 corners of the cartouche, in addition the mark 2GR can be seen separately.
No sign in tardy but test positive.
Thanks
Paul
