[meteorite-list] How to tell which iron is which??

[Allan Treiman]

Hi, meteorite list -

    I've got a question for you. I've been approached for help in  
liquidation
of an estate (in Texas), which has two iron masses labelled as  
meteorites.
But no information on where they came from. Photos attached below.

    They look a lot like irons, and I'm comfortable with a Ni test to  
tell them
from terrestrial iron.

    But -- any suggestions on how to tell which iron meteorite they  
might be?
To my untrained eye, they look a lot like Canyon Diablo. Anyone had this
type of question come up before?

    Thanks for your help.

    Allan
