[meteorite-list] Guanaco and Vaca Muerta

[GERALD FLAHERTY]

Thank you Bernd,
Your expert eye prompted me to use a hand lens and although the 4  I 
received today from Rodigo lack this diagnostic Widmanstaetten pattern, I 
was elated to find these marvelously displayed on the metal nodule in the 
"Four Faces of Vaca Muerta" Riker box, I'd gotten earlier this month from 
David at star-bits!
Being a relative novice I might not have piced these out without your sage 
note.
Thanks once more
Jerry
