Agreed in principle--  Going by the semi-waxy luster, cleavage, and apparent crystal form this is certainly not a pyroxene and highly probable that it is a feldspar.  How this came into being and came to be in this meteorite present some intriguing --probably rare conditions to explain it.

Thanks for presenting it Gary.
