Hi Michael and List, I was not questioning Matt's integrity at all. Both meteorites were found in Texas less than 35 miles apart and are very similar in appearance. Since finely metal-grained H6s with dark matrixes and low shock are rare I feel a pairing must be considered. In any case both Spade and Estacado are beautiful stones.
