Greaves-Winston typology

[Peter Dekker]

Hi all,

I'm trying to learn more about Burmese dha classifications so I can find out more on a number of dha I have.

When digging through Mark Bowditch's site on the matter he often refers to an outdated system that he calls the "Greaves-Winston typology". An internet search found this term only to be used on his site, and on this forum.

I wonder, what is the source of this typology? Who are Greaves and Winston and where can I find the text where they classify these items?

Thanks in advance!
