Hello Walter and List,

Survey of weathering degree of
NWA's presently in my databases:

W0 or W0/1: 10
W1 or W1/2: 62
W2 or W2/3: 66
W3 or W3/4: 72
W4 or W4/5: 14
W5 or W5/6: 10
W6: 03

This survey does not yet include Met.Bull. 86 and
the countless provisional or unclassified NWA's.

Cheers,

Bernd
