Zolensky at JSC. It only lists one piece, which of course is not consistent with the 26.5-gram TKW figure that you say Dean quoted you. Furthermore, the type specimen mass is listed as 15 grams; did Dean really donate more than half the stone to the Smithsonian? As for the 710-gram NWA 1668 (R5, Fa 38.9, Fs 30.2) purchased at the Denver show, it was classified by A. Irving at University of Washington. Shock and weathering are not mentioned for this meteorite in MB #87. As Chauncey Walden pointed out, there is also the 184-gram NWA 1784 (R4/5, S1, W3, Fa 40) classified by M. Bourot-Denise at MNHNP (Paris). --Rob ------_=_NextPart_001_01C31FCC.1D730ED8 Content-Type: text/html; charset="iso-8859-1" <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1"> <META content="MSHTML 5.00.3315.2870" name=GENERATOR></HEAD> <BODY> <DIV><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003>Hi Howard and List,</SPAN></FONT></DIV> <DIV><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003></SPAN></FONT> </DIV> <DIV><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003>On the subject of R5s (and who did their classifications), the 77-grams listed for</SPAN></FONT></DIV> <DIV><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003>NWA 1585 (R5, S2, W1, </SPAN></FONT><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003>Fa 38.8, Fs 32.4) </SPAN></FONT><FONT color=#0000ff face=Arial size=2><SPAN class=587264418-21052003>was classified by M.
