Hi Peter,
While I do not have an Angras, I do have a small amount of these two
extremely fresh and beautiful unpaired angrites:

NWA 4801

NWA 4590 "Tamassint"

It is featured in the November 2008 issue of "Astronomy" Magazine, along
with angrites, NWA 2999 and NWA 4801.

stone:

Enjoy! If anyone would like to receive a list of available specimens of
these two angrites, let me know.
