The Website of Norman Biggs
The recognised authority on British Apothecaries Weights is Professor Norman Biggs, Professor of Mathematics, London School of Economics.
His book "Apothecaries Weights - an Outline Catalogue" is a must for any collector and his numbering system is the standard and that used by this site.
I am most grateful for his kindness and help. For more information on
Norman Biggs please see his web site.

The ISASC is a must for the serious collector of Scales or Weights and their web site should
be up and running soon.

the "English Weights & Measures" site.
