[meteorite-list] Exciting New meteorite material....Mokoia, Wairarapa and Alta Ameem

[Bob WALKER]

Graham

Firstly - congratulations on your new trade acquisitions

However - methinx that you should not be touting Mokoia as a hammer

Its difficult to know who coined the term "hammer" but Michael Blood has 
certainly popularised it as a instantly recognised term in the meteorite 
community

Walter Branch put a wot I feel to be lovely definition of wot a hammer stone 
should be on the hits page now maintained by IMCA

Methinks Mokoia is better described as an observed fall or as my popularised 
term - the nearly nailed

To say it is a hammer when it is not will simply I feel confuse matters and 
misinform the list

Cheers
