What are five minutes in the life of a meteorite, Mike?  ;-)
 
And yes, it is breathtakingly beautiful matter!

Martin, you beat me by about 5 minutes!  :)
 
 List, this must be a wonderful CM2, because it garnered two
 announcements in five minutes.  :)
 
 Count me in as officially on the lookout for some small crumbs of this
 one - contact me off-list if you have some available.
 
 Best regards,
 
 MikeG
